Until recently, we did not have a safe and contained area to actually perform any experiments in. Project FumeHood has changed that, and now provides:<br /> <br /> * A safe fume cupboard, made from chemically inert materials, to do the experiments in<br /> * Providing within the fume cupboard all the amenities you expect in a proper chemistry lab: electric outlets, gas connections, water connections, vacuum takeoff and of course air extraction<br /> * Dedicated, safe storage for glassware and chemicals<br /> * A wide assortment of compatible glassware<br /> * A few necessary chemicals (you will usually have to supply your own specialty chemicals or replace whatever you used, except for proportionally tiny amounts or bulk chemicals)<br /> <br /> The goings-on with the fume hood, at least initially, will mostly be documented on mux's Youtube channel PowerElectronicsBlog. There are various videos, from a public overview of the fumehood to special instructional videos on how to use the fume hood.

This section is periodically updated and cleaned up by the current head honcho: [https://revspace.nl/User:Mux mux]<br /> <br /> * Wed 12 December: thomas is making some copper carbonate<br /> <br /> ==Ground Rules==<br /> <br /> The ground rules for the fumehood are:<br /> * The fumehood must be empty when it’s not in use for an experiment<br /> * Experiments can only be performed with prior approval<br /> * Chemicals need to be correctly and safely stored in the appropriate level of the closet or drawers<br /> * The fumehood can never be used by just one person<br /> * Any experiment has to be attended to at all times, so no overnight experiments (unless you have 2 people stay overnight)<br /> * Fellow spacers should be informed appropriately when an experiment is ongoing<br /> * You are responsible for the chemical waste you generate<br /> <br /> Any broken rule should be immediately noted and if possible righted. If somebody absent-minded stored some widget inside the fume hood, take it out and put it in the person’s samla. If somebody seems to be working by themselves on an experiment, ask if you can be their buddy or inform the kaiser of this. Maybe their chem buddy got sick and they’re still cleaning up but they forgot to tell anyone. <br /> <br /> ===Responsible person===<br /> Everything that happens with the fumehood of any significance should be reported to one responsible person: [https://revspace.nl/User:Mux mux]. By request you can get his e-mail, phone number, Signal, Hangouts, whatever you like. Just ask on IRC or in person, or any other way you see fit.<br /> <br /> ===Experiment planning and approval===<br /> If you intend to do an experiment in the fumehood, you have to make a plan, submit it to the head honcho and get it approved and planned. You will need to:<br /> <br /> * State which reagents you will use and what synthesis you wish to perform (if possible: links to papers/procedures/whatever you’re using)<br /> * Describe the apparatus(es) you will use<br /> * Explain the risks of every step in your synthesis and have contingency plans for when anything goes wrong<br /> * Estimate how long you will want to use the fumehood<br /> * Explain in detail how you will clean everything and how long this will take<br /> * Say when you wish to do your experiment<br /> * Name a person or persons(s) you will be doing the experiment with<br /> <br /> Depending on your experiment, you may either just go ahead, or you may have to schedule a time where either a trained chemist or experienced person is available as well to observe the experiment. <br /> <br /> The focus of any application is on safety and clean-up. You will always be asked to reserve lots of time for prep and cleanup, so keep that in mind.<br /> <br /> The fumehood may be used to ventilate smelly things or accidents in the space safely without planning.<br /> <br /> ==Glassware and Hardware==<br /> <br /> All glassware is standardized to 29/32 ground glass fittings, for which we have appropriate clips. There is currently no up-to-date list of glassware, this is being worked on.<br /> <br /> The fume hood has been designed to work with floating lattice work. In order to build an apparatus, take out a nylon screw in a location where you want to put a bar and screw in one of the threaded M10 rods. You can now use either finger clamps or screw clamps (in the top 2 drawers) to attach glassware to your lattice. There should be plenty of room in the fume hood to build any apparatus you need, up to even fractional distillation setups, all floating above the work surface.<br /> <br /> There is a hot plate stirrer in the top-right drawer. This cannot be suspended, so place your boiling flask close to the work surface. Elevating the hot plate stirrer is not recommended, whatever you use for this is likely not going to be very chemically resistant or sturdy and you will just damage the HPS. Also keep the HPS away from corrosive atmospheres, as it is not a sealed unit!<br /> <br /> Wash and dry glassware, then return it to the correct positions in the drawers. Any broken or missing glassware should be reported, we don't bite!<br /> <br /> Use vaseline on ground glass joints to prevent them sticking together. In experiments that use sulfuric acid, use concentrated sulfuric acid instead. Carefully clean the joints afterwards if you lubricate them with sulfuric acid!<br /> <br /> We have a vacuum pump; it is a carbon vane type that cannot produce a particularly strong vacuum. It has been attacked by an HCl/HNO3 atmosphere and rebuilt, but has suffered significantly. It can be used for vacuum filtrations, but not much more. Use a bubbler when vacuuming off noxious atmospheres!<br /> <br /> ==Chemical storage, allowed and prohibited chemicals==<br /> <br /> The inventory if glassware and hardware is currently being compiled and supplemented. Work in progress.<br /> <br /> Chemical reagents (except for distilled water, isopropanol, waste, and temporarily stored project chemicals) are listed on the inside of the yellow locker cabinet doors to the right of the fume hood. Each bottle is labeled with a number (1-5) corresponding to the appropriate level of the cabinet it should reside in. A digital inventory of the fume hood is also kept on Quartzy: [https://app.quartzy.com/groups/182379/inventory Quartzy: Department of Chemistry]. (you need to log in to access this so ask Mux or PeterC to email you an invite).<br /> <br /> All liquids need secondary containment, this is provided by the glass trays found in cabinets 1,3,4, and 5.<br /> <br /> The bulk of the solids in chemical cabinet 2 are in small samlas, this means that you must carefully take out the samla to access the chemical inside.<br /> <br /> If you need chemicals that we don’t have for a project and don’t know where to source them you can ask mux or PeterC.<br /> <br /> If anything breaks, is added, runs out, and mux is not available to manage this, just put it under the Current Affairs section of this page. <br /> <br /> ===Prohibited chemicals===<br /> Significantly radioactive materials are absolutely forbidden. Yes, we have asked and the answer is a very empathetic no. And if anybody even tries, there are very hefty fines and prison sentences attached. This even goes for depleted ores. <br /> <br /> Any chemicals that are known to attack glass are strictly prohibited. This includes but is not limited to:<br /> <br /> * Molten sodium hydroxide<br /> * Hydrogen fluoride (yes, also very dilute solutions!)<br /> <br /> Additionally, the following chemicals can only be used if absolutely no other options are available and if the responsible person is convince you can handle them responsibly:<br /> <br /> * Fuming nitric acid<br /> * Thermite (which includes ANY exothermic metal-metal oxide reaction, not just aluminum and iron oxide)<br /> <br /> ==Fume hood construction details==<br /> Constructing a fume hood on a tight budget isn’t that easy as we found out. The construction of this fume hood was plagued with things that didn’t quite go right and had to be fixed - so let this story be both a cautionary tale and a guide to doing things better than we did!<br /> <br /> The main function of a fume hood is to be a relatively chemically inert space that contains any hazardous chemicals used or created in chemistry experiments. Things will go wrong, and if they do, the fume hood is there to protect both the operator and the rest of the hackerspace.<br /> <br /> The fume hood provides an approx. 50cm deep, 100cm wide, 95cm tall workspace, with 4 drawers and a lockable (though not particuarly secure) compartment. The fume hood has a single, balanced, vertically travelling window.<br /> <br /> ===Containment and disposal of hazardous substances===<br /> <br /> The fume hood has been constructed to deal with the inevitable spills, smoke production and the like by way of:<br /> <br /> * The extraction fan; rated at approx. 100m3/h, it has the capacity to remove the entire volume of the fume hood every 30 seconds or so. For maximum airflow, make sure the window is NOT completely closed.<br /> * The glass fiber liner. The entire inside of the fume hood is lined in glass fiber reinforced polyester, which is chemically inert to pretty much everything (see prohibited chemicals below). The hardware mounting holes are closed off with nylon screws.<br /> * The lip; any spill (or coolant leakage) up to approx. 20L will be contained by the 4.5-cm lip. <br /> * The glass work surface. Any small spills will run off the raised work surface, keeping the workspace clear to put bottles or other materials on if something goes wrong<br /> * The polycarbonate window. The window is shatter-proof and mounted flexibly, so any explosions should be contained and - worst case - cause the entire window to be blown out instead of lots of small shards.<br /> * The double walls. The fume hood is a double-walled construction - which aside from being convenient for cable routing, also provides effective containment of flying debris and exploding glassware<br /> <br /> ===Other safety features===<br /> <br /> * The electrical system has its own emergency shutdown button and a selective GFCI. (this also means you are NOT allowed to run electricity into the fume hood from anything but the built-in outlets!)<br /> * The fan, light and water can be turned on/off from the operator position in front of the fume hood<br /> * Through-wall, sealed brass water and gas inlets/outlets so you should NEVER need to run hoses through the window<br /> * Suspended latticework to put an apparatus on; any spills will automatically drop down onto the work surface out of the way of other reagents.<br /> <br /> ===So, what’s the problem?===<br /> So far, it seems like the fume hood is pretty sweet! Well, the construction was plagued with more than a few issues:<br /> <br /> * The wooden frame, after assembly, parallellogrammed to make the entire fume hood crooked. This had to be corrected by screwing on a solid steel sheet frame to the front of the fume hood.<br /> * The glass fiber liner did not finish very evenly, even with a layer of (pigmented) gelcoat. Ideally, the fume hood should be a very even glossy white on the inside, but this finish could not be attained. The patchy appearance of the gelcoated glass fiber was fixed by painting the inside, but the paint is of course a lot more reactive than the glass fiber, so in particular acid spills will leave visible marks instead of wiping off easily. This is not a safety hazard, just an aesthetic problem.<br /> * The drawer rails, despite being rated up to 60kg, had trouble dealing even with the weight of the drawers themselves when fully extended and did not operate smoothly. This was fixed with telescoping rails.<br /> * The first window did not operate smoothly. Neither did the hotfix for that window. This was fixed by rebuilding the window on telescoping rails and adding counterweights.<br /> * Including glassware purchases, the budget was overshot by approx. €400<br /> * A filter box was designed (and still hangs on the wall), to be filled with variously activated charcoal filters. Unfortunately, this proved to be quite ineffective as a general purpose filter. The initially planned military-grade filter cans went out of stock the week we tried to purchase some. In the end, we figured maximizing airflow is a better approach than trying to chemically trap any problematic atmospheres.<br /> <br /> These points by themselves aren’t the end of the world - they were mostly consequences of trying to construct a cheap fume hood - which was still successful. The biggest issue was a lack of time. Construction was supposed to be a team effort, but a confluence of factors (most notably: trying to plan anything big in a hackerspace) meant that time for construction was limited and the project proved too big for the main constructor. This let the project timeline drag on for about 9 months longer than it was supposed to, almost axing the project entirely.<br /> <br /> ==Project ideas==<br /> <br /> The fume hood will of course be used for science experiments! Among these may be:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven, using [http://www.sciencedirect.com/science/article/pii/0025540880900124 the original li-ion battery paper] as a guide)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven, we have materials to make cupels and might use Cody's Lab's cyanide from cherry pits-method)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new tea tree oil (3-Terpineol) catalyzed Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes<br /> <br /> == ToDo list ==<br /> <br /> There is always more work to do. <br /> <br /> * Make an inventory of all glassware and label glassware appropriately<br /> * Improve bottom drawer's layout so items can be found more easily (the bottom drawer is primarily for bulk storage of consumables)<br /> * Add a level and a ceiling to the lockable cabinet area<br /> * Re-paint the entire inside of the fume hood so it's all an even color (lip and exhaust are currently significantly discolored)<br /> * Replace pulleys with types that have a cage around the wire (to catch a wire if it falls off)<br /> * Add a faceplate to the top of the fume hood so the pulley mounting and wiring isn't visible and, more importantly, so people aren't as likely to put stuff on top of the fume hood.</div>

If somebody absent-minded stored some widget inside the fume hood, take it out and put it in the person’s samla. If somebody seems to be working by themselves on an experiment, ask if you can be their buddy or inform the kaiser of this. Maybe their chem buddy got sick and they’re still cleaning up but they forgot to tell anyone. <br /> <br /> ===Responsible person===<br /> Everything that happens with the fumehood of any significance should be reported to one responsible person: [https://revspace.nl/User:Mux mux]. By request you can get his e-mail, phone number, Signal, Hangouts, whatever you like. Just ask on IRC or in person, or any other way you see fit.<br /> <br /> ===Experiment planning and approval===<br /> If you intend to do an experiment in the fumehood, you have to make a plan, submit it to the head honcho and get it approved and planned. You will need to:<br /> <br /> * State which reagents you will use and what synthesis you wish to perform (if possible: links to papers/procedures/whatever you’re using)<br /> * Describe the apparatus(es) you will use<br /> * Explain the risks of every step in your synthesis and have contingency plans for when anything goes wrong<br /> * Estimate how long you will want to use the fumehood<br /> * Explain in detail how you will clean everything and how long this will take<br /> * Say when you wish to do your experiment<br /> * Name a person or persons(s) you will be doing the experiment with<br /> <br /> Depending on your experiment, you may either just go ahead, or you may have to schedule a time where either a trained chemist or experienced person is available as well to observe the experiment. <br /> <br /> The focus of any application is on safety and clean-up. You will always be asked to reserve lots of time for prep and cleanup, so keep that in mind.<br /> <br /> The fumehood may be used to ventilate smelly things or accidents in the space safely without planning.<br /> <br /> ==Glassware and Hardware==<br /> <br /> All glassware is standardized to 29/32 ground glass fittings, for which we have appropriate clips. There is currently no up-to-date list of glassware, this is being worked on.<br /> <br /> The fume hood has been designed to work with floating lattice work. In order to build an apparatus, take out a nylon screw in a location where you want to put a bar and screw in one of the threaded M10 rods. You can now use either finger clamps or screw clamps (in the top 2 drawers) to attach glassware to your lattice. There should be plenty of room in the fume hood to build any apparatus you need, up to even fractional distillation setups, all floating above the work surface.<br /> <br /> There is a hot plate stirrer in the top-right drawer. This cannot be suspended, so place your boiling flask close to the work surface. Elevating the hot plate stirrer is not recommended, whatever you use for this is likely not going to be very chemically resistant or sturdy and you will just damage the HPS. Also keep the HPS away from corrosive atmospheres, as it is not a sealed unit!<br /> <br /> Wash and dry glassware, then return it to the correct positions in the drawers. Any broken or missing glassware should be reported, we don't bite!<br /> <br /> Use vaseline on ground glass joints to prevent them sticking together. In experiments that use sulfuric acid, use concentrated sulfuric acid instead. Carefully clean the joints afterwards if you lubricate them with sulfuric acid!<br /> <br /> We have a vacuum pump; it is a carbon vane type that cannot produce a particularly strong vacuum. It has been attacked by an HCl/HNO3 atmosphere and rebuilt, but has suffered significantly. It can be used for vacuum filtrations, but not much more. Use a bubbler when vacuuming off noxious atmospheres!<br /> <br /> ==Chemical storage, allowed and prohibited chemicals==<br /> <br /> The inventory if glassware and hardware is currently being compiled and supplemented. Work in progress.<br /> <br /> Chemical reagents (except for distilled water, isopropanol, waste, and temporarily stored project chemicals) are listed on the inside of the yellow locker cabinet doors to the right of the fume hood. Each bottle is labeled with a number (1-5) corresponding to the appropriate level of the cabinet it should reside in. A digital inventory of the fume hood is also kept on Quartzy: [https://app.quartzy.com/groups/182379/inventory Quartzy: Department of Chemistry]. (you need to log in to access this so ask Mux or PeterC to email you an invite).<br /> <br /> All liquids need secondary containment, this is provided by the glass trays found in cabinets 1,3,4, and 5.<br /> <br /> The bulk of the solids in chemical cabinet 2 are in small samlas, this means that you must carefully take out the samla to access the chemical inside.<br /> <br /> If you need chemicals that we don’t have for a project and don’t know where to source them you can ask mux or PeterC.<br /> <br /> If anything breaks, is added, runs out, and mux is not available to manage this, just put it under the Current Affairs section of this page. <br /> <br /> ===Prohibited chemicals===<br /> Significantly radioactive materials are absolutely forbidden. Yes, we have asked and the answer is a very empathetic no. And if anybody even tries, there are very hefty fines and prison sentences attached. This even goes for depleted ores. <br /> <br /> Any chemicals that are known to attack glass are strictly prohibited. This includes but is not limited to:<br /> <br /> * Molten sodium hydroxide<br /> * Hydrogen fluoride (yes, also very dilute solutions!)<br /> <br /> Additionally, the following chemicals can only be used if absolutely no other options are available and if the responsible person is convince you can handle them responsibly:<br /> <br /> * Fuming nitric acid<br /> * Thermite (which includes ANY exothermic metal-metal oxide reaction, not just aluminum and iron oxide)<br /> <br /> ==Fume hood construction details==<br /> Constructing a fume hood on a tight budget isn’t that easy as we found out. The construction of this fume hood was plagued with things that didn’t quite go right and had to be fixed - so let this story be both a cautionary tale and a guide to doing things better than we did!<br /> <br /> The main function of a fume hood is to be a relatively chemically inert space that contains any hazardous chemicals used or created in chemistry experiments. Things will go wrong, and if they do, the fume hood is there to protect both the operator and the rest of the hackerspace.<br /> <br /> The fume hood provides an approx. 50cm deep, 100cm wide, 95cm tall workspace, with 4 drawers and a lockable (though not particuarly secure) compartment. The fume hood has a single, balanced, vertically travelling window.<br /> <br /> ===Containment and disposal of hazardous substances===<br /> <br /> The fume hood has been constructed to deal with the inevitable spills, smoke production and the like by way of:<br /> <br /> * The extraction fan; rated at approx. 100m3/h, it has the capacity to remove the entire volume of the fume hood every 30 seconds or so. For maximum airflow, make sure the window is NOT completely closed.<br /> * The glass fiber liner. The entire inside of the fume hood is lined in glass fiber reinforced polyester, which is chemically inert to pretty much everything (see prohibited chemicals below). The hardware mounting holes are closed off with nylon screws.<br /> * The lip; any spill (or coolant leakage) up to approx. 20L will be contained by the 4.5-cm lip. <br /> * The glass work surface. Any small spills will run off the raised work surface, keeping the workspace clear to put bottles or other materials on if something goes wrong<br /> * The polycarbonate window. The window is shatter-proof and mounted flexibly, so any explosions should be contained and - worst case - cause the entire window to be blown out instead of lots of small shards.<br /> * The double walls. The fume hood is a double-walled construction - which aside from being convenient for cable routing, also provides effective containment of flying debris and exploding glassware<br /> <br /> ===Other safety features===<br /> <br /> * The electrical system has its own emergency shutdown button and a selective GFCI. (this also means you are NOT allowed to run electricity into the fume hood from anything but the built-in outlets!)<br /> * The fan, light and water can be turned on/off from the operator position in front of the fume hood<br /> * Through-wall, sealed brass water and gas inlets/outlets so you should NEVER need to run hoses through the window<br /> * Suspended latticework to put an apparatus on; any spills will automatically drop down onto the work surface out of the way of other reagents.<br /> <br /> ===So, what’s the problem?===<br /> So far, it seems like the fume hood is pretty sweet! Well, the construction was plagued with more than a few issues:<br /> <br /> * The wooden frame, after assembly, parallellogrammed to make the entire fume hood crooked. This had to be corrected by screwing on a solid steel sheet frame to the front of the fume hood.<br /> * The glass fiber liner did not finish very evenly, even with a layer of (pigmented) gelcoat. Ideally, the fume hood should be a very even glossy white on the inside, but this finish could not be attained. The patchy appearance of the gelcoated glass fiber was fixed by painting the inside, but the paint is of course a lot more reactive than the glass fiber, so in particular acid spills will leave visible marks instead of wiping off easily. This is not a safety hazard, just an aesthetic problem.<br /> * The drawer rails, despite being rated up to 60kg, had trouble dealing even with the weight of the drawers themselves when fully extended and did not operate smoothly. This was fixed with telescoping rails.<br /> * The first window did not operate smoothly. Neither did the hotfix for that window. This was fixed by rebuilding the window on telescoping rails and adding counterweights.<br /> * Including glassware purchases, the budget was overshot by approx. €400<br /> * A filter box was designed (and still hangs on the wall), to be filled with variously activated charcoal filters. Unfortunately, this proved to be quite ineffective as a general purpose filter. The initially planned military-grade filter cans went out of stock the week we tried to purchase some. In the end, we figured maximizing airflow is a better approach than trying to chemically trap any problematic atmospheres.<br /> <br /> These points by themselves aren’t the end of the world - they were mostly consequences of trying to construct a cheap fume hood - which was still successful. The biggest issue was a lack of time. Construction was supposed to be a team effort, but a confluence of factors (most notably: trying to plan anything big in a hackerspace) meant that time for construction was limited and the project proved too big for the main constructor. This let the project timeline drag on for about 9 months longer than it was supposed to, almost axing the project entirely.<br /> <br /> ==Project ideas==<br /> <br /> The fume hood will of course be used for science experiments! Among these may be:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven, using [http://www.sciencedirect.com/science/article/pii/0025540880900124 the original li-ion battery paper] as a guide)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven, we have materials to make cupels and might use Cody's Lab's cyanide from cherry pits-method)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new tea tree oil (3-Terpineol) catalyzed Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes<br /> <br /> == ToDo list ==<br /> <br /> There is always more work to do. <br /> <br /> * Make an inventory of all glassware and label glassware appropriately<br /> * Improve bottom drawer's layout so items can be found more easily (the bottom drawer is primarily for bulk storage of consumables)<br /> * Add a level and a ceiling to the lockable cabinet area<br /> * Re-paint the entire inside of the fume hood so it's all an even color (lip and exhaust are currently significantly discolored)<br /> * Replace pulleys with types that have a cage around the wire (to catch a wire if it falls off)<br /> * Add a faceplate to the top of the fume hood so the pulley mounting and wiring isn't visible and, more importantly, so people aren't as likely to put stuff on top of the fume hood.</div>

This section is periodically updated and cleaned up by the current head honcho: [https://revspace.nl/User:Mux mux]<br /> <br /> * Fumehood can currently NOT be used, preparations for metallic potassium synthesis are currently in the fumehood.<br /> * Mon 26 Nov: metallic potassium synthesis (PeterC and mux)<br /> <br /> ==Ground Rules==<br /> <br /> The ground rules for the fumehood are:<br /> * The fumehood must be empty when it’s not in use for an experiment<br /> * Experiments can only be performed with prior approval<br /> * Chemicals need to be correctly and safely stored in the appropriate level of the closet or drawers<br /> * The fumehood can never be used by just one person<br /> * Any experiment has to be attended to at all times, so no overnight experiments (unless you have 2 people stay overnight)<br /> * Fellow spacers should be informed appropriately when an experiment is ongoing<br /> * You are responsible for the chemical waste you generate<br /> <br /> Any broken rule should be immediately noted and if possible righted. If somebody absent-minded stored some widget inside the fume hood, take it out and put it in the person’s samla. If somebody seems to be working by themselves on an experiment, ask if you can be their buddy or inform the kaiser of this. Maybe their chem buddy got sick and they’re still cleaning up but they forgot to tell anyone. <br /> <br /> ===Responsible person===<br /> Everything that happens with the fumehood of any significance should be reported to one responsible person: [https://revspace.nl/User:Mux mux]. By request you can get his e-mail, phone number, Signal, Hangouts, whatever you like. Just ask on IRC or in person, or any other way you see fit.<br /> <br /> ===Experiment planning and approval===<br /> If you intend to do an experiment in the fumehood, you have to make a plan, submit it to the head honcho and get it approved and planned. You will need to:<br /> <br /> * State which reagents you will use and what synthesis you wish to perform (if possible: links to papers/procedures/whatever you’re using)<br /> * Describe the apparatus(es) you will use<br /> * Explain the risks of every step in your synthesis and have contingency plans for when anything goes wrong<br /> * Estimate how long you will want to use the fumehood<br /> * Explain in detail how you will clean everything and how long this will take<br /> * Say when you wish to do your experiment<br /> * Name a person or persons(s) you will be doing the experiment with<br /> <br /> Depending on your experiment, you may either just go ahead, or you may have to schedule a time where either a trained chemist or experienced person is available as well to observe the experiment. <br /> <br /> The focus of any application is on safety and clean-up. You will always be asked to reserve lots of time for prep and cleanup, so keep that in mind.<br /> <br /> The fumehood may be used to ventilate smelly things or accidents in the space safely without planning.<br /> <br /> ==Glassware and Hardware==<br /> <br /> All glassware is standardized to 29/32 ground glass fittings, for which we have appropriate clips. There is currently no up-to-date list of glassware, this is being worked on.<br /> <br /> The fume hood has been designed to work with floating lattice work. In order to build an apparatus, take out a nylon screw in a location where you want to put a bar and screw in one of the threaded M10 rods. You can now use either finger clamps or screw clamps (in the top 2 drawers) to attach glassware to your lattice. There should be plenty of room in the fume hood to build any apparatus you need, up to even fractional distillation setups, all floating above the work surface.<br /> <br /> There is a hot plate stirrer in the top-right drawer. This cannot be suspended, so place your boiling flask close to the work surface. Elevating the hot plate stirrer is not recommended, whatever you use for this is likely not going to be very chemically resistant or sturdy and you will just damage the HPS. Also keep the HPS away from corrosive atmospheres, as it is not a sealed unit!<br /> <br /> Wash and dry glassware, then return it to the correct positions in the drawers. Any broken or missing glassware should be reported, we don't bite!<br /> <br /> Use vaseline on ground glass joints to prevent them sticking together. In experiments that use sulfuric acid, use concentrated sulfuric acid instead. Carefully clean the joints afterwards if you lubricate them with sulfuric acid!<br /> <br /> We have a vacuum pump; it is a carbon vane type that cannot produce a particularly strong vacuum. It has been attacked by an HCl/HNO3 atmosphere and rebuilt, but has suffered significantly. It can be used for vacuum filtrations, but not much more. Use a bubbler when vacuuming off noxious atmospheres!<br /> <br /> ==Chemical storage, allowed and prohibited chemicals==<br /> <br /> The inventory if glassware and hardware is currently being compiled and supplemented. Work in progress.<br /> <br /> Chemical reagents (except for distilled water, isopropanol, waste, and temporarily stored project chemicals) are listed on the inside of the yellow locker cabinet doors to the right of the fume hood. Each bottle is labeled with a number (1-5) corresponding to the appropriate level of the cabinet it should reside in. A digital inventory of the fume hood is also kept on Quartzy: [https://app.quartzy.com/groups/182379/inventory Quartzy: Department of Chemistry]. (you need to log in to access this so ask Mux or PeterC to email you an invite).<br /> <br /> All liquids need secondary containment, this is provided by the glass trays found in cabinets 1,3,4, and 5.<br /> <br /> The bulk of the solids in chemical cabinet 2 are in small samlas, this means that you must carefully take out the samla to access the chemical inside.<br /> <br /> If you need chemicals that we don’t have for a project and don’t know where to source them you can ask mux or PeterC.<br /> <br /> If anything breaks, is added, runs out, and mux is not available to manage this, just put it under the Current Affairs section of this page. <br /> <br /> ===Prohibited chemicals===<br /> Significantly radioactive materials are absolutely forbidden. Yes, we have asked and the answer is a very empathetic no. And if anybody even tries, there are very hefty fines and prison sentences attached. This even goes for depleted ores. <br /> <br /> Any chemicals that are known to attack glass are strictly prohibited. This includes but is not limited to:<br /> <br /> * Molten sodium hydroxide<br /> * Hydrogen fluoride (yes, also very dilute solutions!)<br /> <br /> Additionally, the following chemicals can only be used if absolutely no other options are available and if the responsible person is convince you can handle them responsibly:<br /> <br /> * Fuming nitric acid<br /> * Thermite (which includes ANY exothermic metal-metal oxide reaction, not just aluminum and iron oxide)<br /> <br /> ==Fume hood construction details==<br /> Constructing a fume hood on a tight budget isn’t that easy as we found out. The construction of this fume hood was plagued with things that didn’t quite go right and had to be fixed - so let this story be both a cautionary tale and a guide to doing things better than we did!<br /> <br /> The main function of a fume hood is to be a relatively chemically inert space that contains any hazardous chemicals used or created in chemistry experiments. Things will go wrong, and if they do, the fume hood is there to protect both the operator and the rest of the hackerspace.<br /> <br /> The fume hood provides an approx. 50cm deep, 100cm wide, 95cm tall workspace, with 4 drawers and a lockable (though not particuarly secure) compartment. The fume hood has a single, balanced, vertically travelling window.<br /> <br /> ===Containment and disposal of hazardous substances===<br /> <br /> The fume hood has been constructed to deal with the inevitable spills, smoke production and the like by way of:<br /> <br /> * The extraction fan; rated at approx. 100m3/h, it has the capacity to remove the entire volume of the fume hood every 30 seconds or so. For maximum airflow, make sure the window is NOT completely closed.<br /> * The glass fiber liner. The entire inside of the fume hood is lined in glass fiber reinforced polyester, which is chemically inert to pretty much everything (see prohibited chemicals below). The hardware mounting holes are closed off with nylon screws.<br /> * The lip; any spill (or coolant leakage) up to approx. 20L will be contained by the 4.5-cm lip. <br /> * The glass work surface. Any small spills will run off the raised work surface, keeping the workspace clear to put bottles or other materials on if something goes wrong<br /> * The polycarbonate window. The window is shatter-proof and mounted flexibly, so any explosions should be contained and - worst case - cause the entire window to be blown out instead of lots of small shards.<br /> * The double walls. The fume hood is a double-walled construction - which aside from being convenient for cable routing, also provides effective containment of flying debris and exploding glassware<br /> <br /> ===Other safety features===<br /> <br /> * The electrical system has its own emergency shutdown button and a selective GFCI. (this also means you are NOT allowed to run electricity into the fume hood from anything but the built-in outlets!)<br /> * The fan, light and water can be turned on/off from the operator position in front of the fume hood<br /> * Through-wall, sealed brass water and gas inlets/outlets so you should NEVER need to run hoses through the window<br /> * Suspended latticework to put an apparatus on; any spills will automatically drop down onto the work surface out of the way of other reagents.<br /> <br /> ===So, what’s the problem?===<br /> So far, it seems like the fume hood is pretty sweet! Well, the construction was plagued with more than a few issues:<br /> <br /> * The wooden frame, after assembly, parallellogrammed to make the entire fume hood crooked. This had to be corrected by screwing on a solid steel sheet frame to the front of the fume hood.<br /> * The glass fiber liner did not finish very evenly, even with a layer of (pigmented) gelcoat. Ideally, the fume hood should be a very even glossy white on the inside, but this finish could not be attained. The patchy appearance of the gelcoated glass fiber was fixed by painting the inside, but the paint is of course a lot more reactive than the glass fiber, so in particular acid spills will leave visible marks instead of wiping off easily. This is not a safety hazard, just an aesthetic problem.<br /> * The drawer rails, despite being rated up to 60kg, had trouble dealing even with the weight of the drawers themselves when fully extended and did not operate smoothly. This was fixed with telescoping rails.<br /> * The first window did not operate smoothly. Neither did the hotfix for that window. This was fixed by rebuilding the window on telescoping rails and adding counterweights.<br /> * Including glassware purchases, the budget was overshot by approx. €400<br /> * A filter box was designed (and still hangs on the wall), to be filled with variously activated charcoal filters. Unfortunately, this proved to be quite ineffective as a general purpose filter. The initially planned military-grade filter cans went out of stock the week we tried to purchase some. In the end, we figured maximizing airflow is a better approach than trying to chemically trap any problematic atmospheres.<br /> <br /> These points by themselves aren’t the end of the world - they were mostly consequences of trying to construct a cheap fume hood - which was still successful. The biggest issue was a lack of time. Construction was supposed to be a team effort, but a confluence of factors (most notably: trying to plan anything big in a hackerspace) meant that time for construction was limited and the project proved too big for the main constructor. This let the project timeline drag on for about 9 months longer than it was supposed to, almost axing the project entirely.<br /> <br /> ==Project ideas==<br /> <br /> The fume hood will of course be used for science experiments! Among these may be:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven, using [http://www.sciencedirect.com/science/article/pii/0025540880900124 the original li-ion battery paper] as a guide)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven, we have materials to make cupels and might use Cody's Lab's cyanide from cherry pits-method)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new tea tree oil (3-Terpineol) catalyzed Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes<br /> <br /> == ToDo list ==<br /> <br /> There is always more work to do. <br /> <br /> * Make an inventory of all glassware and label glassware appropriately<br /> * Improve bottom drawer's layout so items can be found more easily (the bottom drawer is primarily for bulk storage of consumables)<br /> * Add a level and a ceiling to the lockable cabinet area<br /> * Re-paint the entire inside of the fume hood so it's all an even color (lip and exhaust are currently significantly discolored)<br /> * Replace pulleys with types that have a cage around the wire (to catch a wire if it falls off)<br /> * Add a faceplate to the top of the fume hood so the pulley mounting and wiring isn't visible and, more importantly, so people aren't as likely to put stuff on top of the fume hood.</div>

If somebody absent-minded stored some widget inside the fume hood, take it out and put it in the person’s samla. If somebody seems to be working by themselves on an experiment, ask if you can be their buddy or inform the kaiser of this. Maybe their chem buddy got sick and they’re still cleaning up but they forgot to tell anyone. <br /> <br /> ===Responsible person===<br /> Everything that happens with the fumehood of any significance should be reported to one responsible person: [https://revspace.nl/User:Mux mux]. By request you can get his e-mail, phone number, Signal, Hangouts, whatever you like. Just ask on IRC or in person, or any other way you see fit.<br /> <br /> ===Experiment planning and approval===<br /> If you intend to do an experiment in the fumehood, you have to make a plan, submit it to the head honcho and get it approved and planned. You will need to:<br /> <br /> * State which reagents you will use and what synthesis you wish to perform (if possible: links to papers/procedures/whatever you’re using)<br /> * Describe the apparatus(es) you will use<br /> * Explain the risks of every step in your synthesis and have contingency plans for when anything goes wrong<br /> * Estimate how long you will want to use the fumehood<br /> * Explain in detail how you will clean everything and how long this will take<br /> * Say when you wish to do your experiment<br /> * Name a person or persons(s) you will be doing the experiment with<br /> <br /> Depending on your experiment, you may either just go ahead, or you may have to schedule a time where either a trained chemist or experienced person is available as well to observe the experiment. <br /> <br /> The focus of any application is on safety and clean-up. You will always be asked to reserve lots of time for prep and cleanup, so keep that in mind.<br /> <br /> The fumehood may be used to ventilate smelly things or accidents in the space safely without planning.<br /> <br /> ==Glassware and Hardware==<br /> <br /> All glassware is standardized to 29/32 ground glass fittings, for which we have appropriate clips. There is currently no up-to-date list of glassware, this is being worked on.<br /> <br /> The fume hood has been designed to work with floating lattice work. In order to build an apparatus, take out a nylon screw in a location where you want to put a bar and screw in one of the threaded M10 rods. You can now use either finger clamps or screw clamps (in the top 2 drawers) to attach glassware to your lattice. There should be plenty of room in the fume hood to build any apparatus you need, up to even fractional distillation setups, all floating above the work surface.<br /> <br /> There is a hot plate stirrer in the top-right drawer. This cannot be suspended, so place your boiling flask close to the work surface. Elevating the hot plate stirrer is not recommended, whatever you use for this is likely not going to be very chemically resistant or sturdy and you will just damage the HPS. Also keep the HPS away from corrosive atmospheres, as it is not a sealed unit!<br /> <br /> Wash and dry glassware, then return it to the correct positions in the drawers. Any broken or missing glassware should be reported, we don't bite!<br /> <br /> Use vaseline on ground glass joints to prevent them sticking together. In experiments that use sulfuric acid, use concentrated sulfuric acid instead. Carefully clean the joints afterwards if you lubricate them with sulfuric acid!<br /> <br /> We have a vacuum pump; it is a carbon vane type that cannot produce a particularly strong vacuum. It has been attacked by an HCl/HNO3 atmosphere and rebuilt, but has suffered significantly. It can be used for vacuum filtrations, but not much more. Use a bubbler when vacuuming off noxious atmospheres!<br /> <br /> ==Chemical storage, allowed and prohibited chemicals==<br /> <br /> The inventory if glassware and hardware is currently being compiled and supplemented. Work in progress.<br /> <br /> Chemical reagents (except for distilled water, isopropanol, waste, and temporarily stored project chemicals) are listed on the inside of the yellow locker cabinet doors to the right of the fume hood. Each bottle is labeled with a number (1-5) corresponding to the appropriate level of the cabinet it should reside in. A digital inventory of the fume hood is also kept on Quartzy: [https://app.quartzy.com/groups/182379/inventory Quartzy: Department of Chemistry]. (you need to log in to access this so ask Mux or PeterC to email you an invite).<br /> <br /> All liquids need secondary containment, this is provided by the glass trays found in cabinets 1,3,4, and 5.<br /> <br /> The bulk of the solids in chemical cabinet 2 are in small samlas, this means that you must carefully take out the samla to access the chemical inside.<br /> <br /> If you need chemicals that we don’t have for a project and don’t know where to source them you can ask mux or PeterC.<br /> <br /> If anything breaks, is added, runs out, and mux is not available to manage this, just put it under the Current Affairs section of this page. <br /> <br /> ===Prohibited chemicals===<br /> Any chemicals that are known to attack glass are strictly prohibited. This includes but is not limited to:<br /> <br /> * Molten sodium hydroxide<br /> * Hydrogen fluoride (yes, also very dilute solutions!)<br /> <br /> Additionally, the following chemicals can only be used if absolutely no other options are available and if the responsible person is convince you can handle them responsibly:<br /> <br /> * Fuming nitric acid<br /> * Thermite (which includes ANY exothermic metal-metal oxide reaction, not just aluminum and iron oxide)<br /> <br /> ==Fume hood construction details==<br /> Constructing a fume hood on a tight budget isn’t that easy as we found out. The construction of this fume hood was plagued with things that didn’t quite go right and had to be fixed - so let this story be both a cautionary tale and a guide to doing things better than we did!<br /> <br /> The main function of a fume hood is to be a relatively chemically inert space that contains any hazardous chemicals used or created in chemistry experiments. Things will go wrong, and if they do, the fume hood is there to protect both the operator and the rest of the hackerspace.<br /> <br /> The fume hood provides an approx. 50cm deep, 100cm wide, 95cm tall workspace, with 4 drawers and a lockable (though not particuarly secure) compartment. The fume hood has a single, balanced, vertically travelling window.<br /> <br /> ===Containment and disposal of hazardous substances===<br /> <br /> The fume hood has been constructed to deal with the inevitable spills, smoke production and the like by way of:<br /> <br /> * The extraction fan; rated at approx. 100m3/h, it has the capacity to remove the entire volume of the fume hood every 30 seconds or so. For maximum airflow, make sure the window is NOT completely closed.<br /> * The glass fiber liner. The entire inside of the fume hood is lined in glass fiber reinforced polyester, which is chemically inert to pretty much everything (see prohibited chemicals below). The hardware mounting holes are closed off with nylon screws.<br /> * The lip; any spill (or coolant leakage) up to approx. 20L will be contained by the 4.5-cm lip. <br /> * The glass work surface. Any small spills will run off the raised work surface, keeping the workspace clear to put bottles or other materials on if something goes wrong<br /> * The polycarbonate window. The window is shatter-proof and mounted flexibly, so any explosions should be contained and - worst case - cause the entire window to be blown out instead of lots of small shards.<br /> * The double walls. The fume hood is a double-walled construction - which aside from being convenient for cable routing, also provides effective containment of flying debris and exploding glassware<br /> <br /> ===Other safety features===<br /> <br /> * The electrical system has its own emergency shutdown button and a selective GFCI. (this also means you are NOT allowed to run electricity into the fume hood from anything but the built-in outlets!)<br /> * The fan, light and water can be turned on/off from the operator position in front of the fume hood<br /> * Through-wall, sealed brass water and gas inlets/outlets so you should NEVER need to run hoses through the window<br /> * Suspended latticework to put an apparatus on; any spills will automatically drop down onto the work surface out of the way of other reagents.<br /> <br /> ===So, what’s the problem?===<br /> So far, it seems like the fume hood is pretty sweet! Well, the construction was plagued with more than a few issues:<br /> <br /> * The wooden frame, after assembly, parallellogrammed to make the entire fume hood crooked. This had to be corrected by screwing on a solid steel sheet frame to the front of the fume hood.<br /> * The glass fiber liner did not finish very evenly, even with a layer of (pigmented) gelcoat. Ideally, the fume hood should be a very even glossy white on the inside, but this finish could not be attained. The patchy appearance of the gelcoated glass fiber was fixed by painting the inside, but the paint is of course a lot more reactive than the glass fiber, so in particular acid spills will leave visible marks instead of wiping off easily. This is not a safety hazard, just an aesthetic problem.<br /> * The drawer rails, despite being rated up to 60kg, had trouble dealing even with the weight of the drawers themselves when fully extended and did not operate smoothly. This was fixed with telescoping rails.<br /> * The first window did not operate smoothly. Neither did the hotfix for that window. This was fixed by rebuilding the window on telescoping rails and adding counterweights.<br /> * Including glassware purchases, the budget was overshot by approx. €400<br /> * A filter box was designed (and still hangs on the wall), to be filled with variously activated charcoal filters. Unfortunately, this proved to be quite ineffective as a general purpose filter. The initially planned military-grade filter cans went out of stock the week we tried to purchase some. In the end, we figured maximizing airflow is a better approach than trying to chemically trap any problematic atmospheres.<br /> <br /> These points by themselves aren’t the end of the world - they were mostly consequences of trying to construct a cheap fume hood - which was still successful. The biggest issue was a lack of time. Construction was supposed to be a team effort, but a confluence of factors (most notably: trying to plan anything big in a hackerspace) meant that time for construction was limited and the project proved too big for the main constructor. This let the project timeline drag on for about 9 months longer than it was supposed to, almost axing the project entirely.<br /> <br /> ==Project ideas==<br /> <br /> The fume hood will of course be used for science experiments! Among these may be:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven, using [http://www.sciencedirect.com/science/article/pii/0025540880900124 the original li-ion battery paper] as a guide)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven, we have materials to make cupels and might use Cody's Lab's cyanide from cherry pits-method)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new tea tree oil (3-Terpineol) catalyzed Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes<br /> <br /> == ToDo list ==<br /> <br /> There is always more work to do. <br /> <br /> * Make an inventory of all glassware and label glassware appropriately<br /> * Improve bottom drawer's layout so items can be found more easily (the bottom drawer is primarily for bulk storage of consumables)<br /> * Add a level and a ceiling to the lockable cabinet area<br /> * Re-paint the entire inside of the fume hood so it's all an even color (lip and exhaust are currently significantly discolored)<br /> * Replace pulleys with types that have a cage around the wire (to catch a wire if it falls off)<br /> * Add a faceplate to the top of the fume hood so the pulley mounting and wiring isn't visible and, more importantly, so people aren't as likely to put stuff on top of the fume hood.</div>

You will need to:<br /> <br /> * State which reagents you will use and what synthesis you wish to perform (if possible: links to papers/procedures/whatever you’re using)<br /> * Describe the apparatus(es) you will use<br /> * Explain the risks of every step in your synthesis and have contingency plans for when anything goes wrong<br /> * Estimate how long you will want to use the fumehood<br /> * Explain in detail how you will clean everything and how long this will take<br /> * Say when you wish to do your experiment<br /> * Name a person or persons(s) you will be doing the experiment with<br /> <br /> Depending on your experiment, you may either just go ahead, or you may have to schedule a time where either a trained chemist or experienced person is available as well to observe the experiment. <br /> <br /> The focus of any application is on safety and clean-up. You will always be asked to reserve lots of time for prep and cleanup, so keep that in mind.<br /> <br /> The fumehood may be used to ventilate smelly things or accidents in the space safely without planning.<br /> <br /> ==Glassware and Hardware==<br /> <br /> All glassware is standardized to 29/32 ground glass fittings, for which we have appropriate clips. There is currently no up-to-date list of glassware, this is being worked on.<br /> <br /> The fume hood has been designed to work with floating lattice work. In order to build an apparatus, take out a nylon screw in a location where you want to put a bar and screw in one of the threaded M10 rods. You can now use either finger clamps or screw clamps (in the top 2 drawers) to attach glassware to your lattice. There should be plenty of room in the fume hood to build any apparatus you need, up to even fractional distillation setups, all floating above the work surface.<br /> <br /> There is a hot plate stirrer in the top-right drawer. This cannot be suspended, so place your boiling flask close to the work surface. Elevating the hot plate stirrer is not recommended, whatever you use for this is likely not going to be very chemically resistant or sturdy and you will just damage the HPS. Also keep the HPS away from corrosive atmospheres, as it is not a sealed unit!<br /> <br /> Wash and dry glassware, then return it to the correct positions in the drawers. Any broken or missing glassware should be reported, we don't bite!<br /> <br /> Use vaseline on ground glass joints to prevent them sticking together. In experiments that use sulfuric acid, use concentrated sulfuric acid instead. Carefully clean the joints afterwards if you lubricate them with sulfuric acid!<br /> <br /> We have a vacuum pump; it is a carbon vane type that cannot produce a particularly strong vacuum. It has been attacked by an HCl/HNO3 atmosphere and rebuilt, but has suffered significantly. It can be used for vacuum filtrations, but not much more. Use a bubbler when vacuuming off noxious atmospheres!<br /> <br /> ==Chemical storage, allowed and prohibited chemicals==<br /> <br /> The inventory if glassware and hardware is currently being compiled and supplemented. Work in progress.<br /> <br /> Chemical reagents (except for distilled water, isopropanol, waste, and temporarily stored project chemicals) are listed on the inside of the yellow locker cabinet doors to the right of the fume hood. Each bottle is labeled with a number (1-5) corresponding to the appropriate level of the cabinet it should reside in. A digital inventory of the fume hood is also kept on Quartzy: [https://app.quartzy.com/groups/182379/inventory Quartzy: Department of Chemistry]. (you need to log in to access this so ask Mux or PeterC to email you an invite).<br /> <br /> All liquids need secondary containment, this is provided by the glass trays found in cabinets 1,3,4, and 5.<br /> <br /> The bulk of the solids in chemical cabinet 2 are in small samlas, this means that you must carefully take out the samla to access the chemical inside.<br /> <br /> If you need chemicals that we don’t have for a project and don’t know where to source them you can ask mux or PeterC.<br /> <br /> If anything breaks, is added, runs out, and mux is not available to manage this, just put it under the Current Affairs section of this page. <br /> <br /> ===Prohibited chemicals===<br /> Any chemicals that are known to attack glass are strictly prohibited. This includes but is not limited to:<br /> <br /> * Molten sodium hydroxide<br /> * Hydrogen fluoride (yes, also very dilute solutions!)<br /> <br /> Additionally, the following chemicals can only be used if absolutely no other options are available and if the responsible person is convince you can handle them responsibly:<br /> <br /> * Fuming nitric acid<br /> * Thermite (which includes ANY exothermic metal-metal oxide reaction, not just aluminum and iron oxide)<br /> <br /> ==Fume hood construction details==<br /> Constructing a fume hood on a tight budget isn’t that easy as we found out. The construction of this fume hood was plagued with things that didn’t quite go right and had to be fixed - so let this story be both a cautionary tale and a guide to doing things better than we did!<br /> <br /> The main function of a fume hood is to be a relatively chemically inert space that contains any hazardous chemicals used or created in chemistry experiments. Things will go wrong, and if they do, the fume hood is there to protect both the operator and the rest of the hackerspace.<br /> <br /> The fume hood provides an approx. 50cm deep, 100cm wide, 95cm tall workspace, with 4 drawers and a lockable (though not particuarly secure) compartment. The fume hood has a single, balanced, vertically travelling window.<br /> <br /> ===Containment and disposal of hazardous substances===<br /> <br /> The fume hood has been constructed to deal with the inevitable spills, smoke production and the like by way of:<br /> <br /> * The extraction fan; rated at approx. 100m3/h, it has the capacity to remove the entire volume of the fume hood every 30 seconds or so. For maximum airflow, make sure the window is NOT completely closed.<br /> * The glass fiber liner. The entire inside of the fume hood is lined in glass fiber reinforced polyester, which is chemically inert to pretty much everything (see prohibited chemicals below). The hardware mounting holes are closed off with nylon screws.<br /> * The lip; any spill (or coolant leakage) up to approx. 20L will be contained by the 4.5-cm lip. <br /> * The glass work surface. Any small spills will run off the raised work surface, keeping the workspace clear to put bottles or other materials on if something goes wrong<br /> * The polycarbonate window. The window is shatter-proof and mounted flexibly, so any explosions should be contained and - worst case - cause the entire window to be blown out instead of lots of small shards.<br /> * The double walls. The fume hood is a double-walled construction - which aside from being convenient for cable routing, also provides effective containment of flying debris and exploding glassware<br /> <br /> ===Other safety features===<br /> <br /> * The electrical system has its own emergency shutdown button and a selective GFCI. (this also means you are NOT allowed to run electricity into the fume hood from anything but the built-in outlets!)<br /> * The fan, light and water can be turned on/off from the operator position in front of the fume hood<br /> * Through-wall, sealed brass water and gas inlets/outlets so you should NEVER need to run hoses through the window<br /> * Suspended latticework to put an apparatus on; any spills will automatically drop down onto the work surface out of the way of other reagents.<br /> <br /> ===So, what’s the problem?===<br /> So far, it seems like the fume hood is pretty sweet! Well, the construction was plagued with more than a few issues:<br /> <br /> * The wooden frame, after assembly, parallellogrammed to make the entire fume hood crooked. This had to be corrected by screwing on a solid steel sheet frame to the front of the fume hood.<br /> * The glass fiber liner did not finish very evenly, even with a layer of (pigmented) gelcoat. Ideally, the fume hood should be a very even glossy white on the inside, but this finish could not be attained. The patchy appearance of the gelcoated glass fiber was fixed by painting the inside, but the paint is of course a lot more reactive than the glass fiber, so in particular acid spills will leave visible marks instead of wiping off easily. This is not a safety hazard, just an aesthetic problem.<br /> * The drawer rails, despite being rated up to 60kg, had trouble dealing even with the weight of the drawers themselves when fully extended and did not operate smoothly. This was fixed with telescoping rails.<br /> * The first window did not operate smoothly. Neither did the hotfix for that window. This was fixed by rebuilding the window on telescoping rails and adding counterweights.<br /> * Including glassware purchases, the budget was overshot by approx. €400<br /> * A filter box was designed (and still hangs on the wall), to be filled with variously activated charcoal filters. Unfortunately, this proved to be quite ineffective as a general purpose filter. The initially planned military-grade filter cans went out of stock the week we tried to purchase some. In the end, we figured maximizing airflow is a better approach than trying to chemically trap any problematic atmospheres.<br /> <br /> These points by themselves aren’t the end of the world - they were mostly consequences of trying to construct a cheap fume hood - which was still successful. The biggest issue was a lack of time. Construction was supposed to be a team effort, but a confluence of factors (most notably: trying to plan anything big in a hackerspace) meant that time for construction was limited and the project proved too big for the main constructor. This let the project timeline drag on for about 9 months longer than it was supposed to, almost axing the project entirely.<br /> <br /> ==Project ideas==<br /> <br /> The fume hood will of course be used for science experiments! Among these may be:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven, using [http://www.sciencedirect.com/science/article/pii/0025540880900124 the original li-ion battery paper] as a guide)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven, we have materials to make cupels and might use Cody's Lab's cyanide from cherry pits-method)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new tea tree oil (3-Terpineol) catalyzed Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes<br /> <br /> == ToDo list ==<br /> <br /> There is always more work to do. <br /> <br /> * Make an inventory of all glassware and label glassware appropriately<br /> * Improve bottom drawer's layout so items can be found more easily (the bottom drawer is primarily for bulk storage of consumables)<br /> * Add a level and a ceiling to the lockable cabinet area<br /> * Re-paint the entire inside of the fume hood so it's all an even color (lip and exhaust are currently significantly discolored)<br /> * Replace pulleys with types that have a cage around the wire (to catch a wire if it falls off)<br /> * Add a faceplate to the top of the fume hood so the pulley mounting and wiring isn't visible and, more importantly, so people aren't as likely to put stuff on top of the fume hood.</div>

Een groot nadeel van deze voertuigen is dat accu's in vergelijking met een brandstoftank nog altijd wat beperkt zijn in hoeveel energie ze kunnen vasthouden. Om lekker rond te kunnen karren heb je dus wat vaker toegang nodig tot een [https://oplaadpalen.nl/ stopcontact] dan dat je een brandstof auto moet tanken. Niet alleen vaker, maar ook langer, want het laden duurt even.<br /> <br /> Omdat het laden even duurt is het daarom handig een stopcontact te hebben op de plek waar je heen gaat. Terwijl je ergens bent kan je auto dan opladen. Revspace is zo'n plek waar ik regelmatig ben, maar tot nu toe geen &quot;echt&quot; laadpunt was.<br /> <br /> Sinds september 2016 heb ik een [https://en.wikipedia.org/wiki/Renault_Twizy Renault Twizy]. Daar heb je eigenlijk geen &quot;echt&quot; laadpunt voor nodig, want hij laad slechts met 230VAC 10A (enkele fase). Er zit dan ook een doodnormale [https://en.wikipedia.org/wiki/Schuko Schuko] stekker aan, en niet de in Europa voor auto's bekende [https://en.wikipedia.org/wiki/Type_2_connector Mennekes Type 2]. Wanneer ik wat laag aan de acculading zat deed ik mijn Twizy dan ook via een normaal (geschikt) verlengsnoer opladen bij Revspace. Vanaf het begin waren er al geluiden dat dit problemen kon gaan geven omdat het niet echt als &quot;fair use&quot; te verkopen valt aan de partij waarvan Revspace het pand van huurt. Maar gezien de Twizy niet een &quot;echte&quot; auto was en ik het niet heel vaak deed, werd een oogje toe geknepen.<br /> <br /> Sinds ergens begin 2018 heeft [[mux]] echter ook een elektrische kar, namelijk een 1st gen.

Dank aan laadpunt.nl daarvoor.<br /> <br /> === Keba P20 ===<br /> [[File:Keba_P20_tweedehandsje.jpg|200px|thumb|right|De Keba P20 gekocht door merethan]]<br /> Het apparaat betreft een [https://www.keba.com/web/downloads/e-mobility/KeContact_KCP20_30_ih_en.pdf Keba KeContact P20]. Hij heeft reeds ruim 2 jaar dienst gedaan bij de vorige eigenaar.

De installatiehandleiding bevat een handig tabelletje om dat te decoderen. Het komt neer op het volgende:<br /> KeContact, model P20, Europese uitvoering, met een Socket (ipv vaste kabel), 2 = Mennekes Type-2, 4 = 32A versie, 00 = 0 meter kabel (duh..), 1 = b-series model, 0 = &quot;Contactor electrics&quot; (wut??), 00R = met RFID uitgevoerd.<br /> <br /> Het betreft dus, gezien het 3-fase 230V op 32A is, een 22kW laadpunt.<br /> <br /> ==== Installatie ====<br /> Het apparaat moet upstream afgezekerd worden met een automaat die bij de specs van de bekabeling past en een eigen aardlekschakelaar. Ook moet het maximale laadvermogen dmv DIP-switches ingesteld worden, zodat de paal dit kan communiceren aan de auto.<br /> <br /> == Interfaces ==<br /> Het apparaat heeft meerdere interfaces via welke het interactie heeft met de rest van de wereld.<br /> <br /> === Mennekes Type 2 plug met SAE J1772 signallering ===<br /> !! Mux moet deze sectie nog fact-checken en aanvullen !!&lt;br&gt;<br /> De meest elementaire interface aan het laadpunt is het stopcontact voor de auto: De [https://en.wikipedia.org/wiki/Type_2_connector Mennekes Type 2] connector. Deze bevat naast een PE, N, L1, L2 en L3 (de pinnen die je kent van krachtstroom) ook nog de pinnen PP (proximity pilot) en CP (control pilot). Via PP en CP communiceren de auto, de kabel en het laadsysteem hoeveel vermogen er getrokken mag worden. De logica hierachter is echt heel low-tech en niet uniek voor deze plug. Het &quot;protocol&quot; is namelijk overgenomen van een andere standaard: De Japans/Amerikaanse [https://en.wikipedia.org/wiki/SAE_J1772 SAE J1772] plug.<br /> <br /> Via de PP pin laat de kabel (de stekker eigenlijk) weten voor hoeveel ampère de kabel geschikt is. Dit werkt zeer low-tech: Een bepaalde weerstand tussen de +12V PP pin en de PE pin codeert van welke klasse de kabel is. Via deze pin kan zowel de auto als het laadstation dus ook detecteren wanneer er een kabel ingeplugd is. De PP pin is ook korter dan de andere pinnen, zodat het laadstation of de auto de stroom kan afschakelen voordat de rest van de pinnen contact verliezen (dit om vonken te voorkomen). De PP pin is niet van de ene naar de andere kant van de kabel verbonden.<br /> <br /> De CP pin is wel verbonden door de kabel heen, wat de auto en het laadpunt in staat stelt om te communiceren met elkaar. Again, dit werkt zeer low-tech: Het laadpunt zet een square-wave van ±12V (-12V tot +12V) op de CP pin, met een frequentie van 1Khz. Als de PWM 1Khz. is betekent dat dat de auto &quot;vol vermogen&quot; mag trekken. Hoe lager de frequentie, hoe minder amps de auto mag trekken. Online zijn tabellen te vinden van welke PWM cycle hoeveel ampères betekent.<br /> <br /> De CP pin is aan de auto kant verbonden met de PE pin via een weerstand en een diode. Omdat maar de helft van de ±12V square-wave afgevlakt wordt (diode) weet het laadstation dat het snoer ook echt in een auto zit en niet in de regen ligt. De weerstand die de auto tussen CP en PE plaatst codeert verschillende &quot;staten&quot; waarin de auto zich bevind. Zo is er bijvoorbeeld een specifieke weerstand waarmee de auto aan het laadsation aangeeft dat hij wil gaan laden. Online zijn tabellen te vinden met welke weerstand welke staat codeert.<br /> <br /> Meer diepgaande uitleg en tabellen van coderingen is [https://en.wikipedia.org/wiki/SAE_J1772#Signaling op Wikipedia] te vinden.<br /> <br /> Voor de duidelijkheid: Het laadpunt is enkel een circuit breaker. Het laadpunt doet niets in de trand van power duty cycle regeling. Als de auto meer amps trekt dan het door het laadpunt opgegeven maximum, gaat de stroom gewoon uit.<br /> <br /> === GreenPhy protocol ===<br /> Het laadstation ondersteunt ook PLC (Power Line Communication) met de auto dmv het [https://en.wikipedia.org/wiki/HomePlug#HomePlug_Green_PHY GreenPhy protocol]. Voor wat ik er nu van begrijp stelt dat de auto in staat om via de AC kabels op 10mbit te communiceren met het LAN waar het laadpunt aan vast zit. Zeer vergelijkbaar met &quot;power line ethernet&quot; wat je binnen je huis kunt doen, als je te lui bent om kabels te trekken.<br /> <br /> === RFID ===<br /> Bijna alle laadstations hebben een methode voor authorisatie/authenticatie. Het authorisatie/authenticatiesysteem van het door mij gekochte model werkt op basis van RFID tokens. RFID functionaliteit wordt verzorgd door een [http://www.hopt-schuler.com/33771/Products/Card-Readers/RFID-card-readers/RFID-card-readers/881/productlist.aspx ddm Hopt+Schuler 881 module] ([https://www.microtron.be/wp-content/uploads/2016/10/Hopt-Schuler-881.pdf datasheet]). Deze reader is compatible met Mifare/ISO14443/ISO15693 tokens. Voor zover ik het systeem nu begrijp blaft de module gewoon het serienummer van de gepresenteerde token over een RS232 TTL lijn heen en dat is dan de sleutel.<br /> <br /> === Enable-input ===<br /> Binnenin het laadstation zit een enable-input (terminal X1) voor interfacing met een ander systeem. Door deze terminal kort te sluiten is het systeem &quot;enabled&quot;. Hierin slaat &quot;enabled&quot; niet op authorisatie: Deze input schakelt het laden aan of uit, maar voorkomt aankoppelen niet. Dus als de enable-input onderbroken (uit) is, en iemand koppelt een kabel/auto aan, dan wordt die wel gelocked en begint initialisatie van het laadproces. Laden (stroom leveren) begint echter pas als je X1 kortsluit. (Dat zou je bijvoorbeeld kunnen gebruiken icm een zonnepanelen systeem, zodat je enkel overcapaciteit in je auto laad.) De enable-input is dus geen access control systeem of te gebruiken om een access control systeem op aan te sluiten.<br /> <br /> === Ethernet ===<br /> De Keba P20 heeft een ethernetpoortje (terminal X3). De IP instellingen zijn te regelen met de DIP-switches. Momenteel gebruikt het apparaat 192.168.25.11 als adres.<br /> <br /> ==== UDP input ====<br /> Keba laadpunten ondersteunen volgens de UDP programmers manual een setje commando's die je via ethernet kunt sturen. Dit zijn simpele tekst-gebaseerde commando's over UDP, op poort 7090. Open een shell met 'netcat -l -p 7090 -u -b 192.168.25.11 7090' om te luisteren, ga in een andere shell commando's sturen met 'echo -n &quot;[command]&quot; | netcat -q 0 -u 192.168.25.11 7090', en je bent in business.<br /> <br /> De door mij gekochte versie is echter het instapmodel, en ondersteunt daarom vrijwel niks van wat in de UDP manual van Keba staat. Dit is waarschijnlijk slechts een upselling scheme wat enkel in de software verankerd is, maar voor nu even waar we het mee moeten doen. De enige commando's waar mijn model zover op gereageerd heeft is i, waarop hij antwoord met &quot;Firmware: KEBA P20 v 2.5a3 (160613-061001)&quot;, en report 1, waarop je iets meer info terug krijgt (ook serienummer &amp; modelnummer). En dat was het.<br /> <br /> ==== UDP output ====<br /> De ethernetpoort is niet geheel waardeloos, want hij doet wel nuttige UDP broadcasts. Bij elke status verandering doet hij een bijpassende broadcast met de veranderde waarden. Denk aan de toestand van het apparaat (wachten/aankoppelen/laden etc.), het koppelen/ontkoppelen van de kabel en/of auto, wanneer er authorisatie is (RFID/UDP), enable input (X1) open/dicht, en een verandering in hoeveelheid geleverde energie. Zie de UDP programmers guide van Keba voor een overzicht &amp; uitleg.<br /> <br /> Hij gaat overigens pas broadcasts geven nadat je even tegen hem gepraat heb. Het is net een dronkenlap in een bar: Je moet even één vraag stellen maar daarna houd hij niet meer op met praten.<br /> <br /> ==== HTTP ====<br /> Op poort 80 zit een webserver, die een pagina serveert waar wat statistieken op staan vergelijkbaar met wat via UDP broadcasts gepubliceert wordt.<br /> <br /> ==== OCPP ====<br /> Het apparaat lijkt iets van &quot;communication hub mode&quot; ofzo met een KeContact C10 communication hub te kunnen via OCPP. Geen idee wat het precies is, maar wellicht het onderzoeken waard. Het lijkt iets te zijn waarbij je &quot;intelligent&quot; energie kunt verdelen, indien je een systeem heb met meerdere van deze laadstations.<br /> <br /> == Interfacing met de space ==<br /> Wat ik wil maken is dat elke deelnemer zich met zijn/haar [[Secure_iButton]] kan authenticeren op het laadstation en dat de kosten voor de geleverde energie worden afgerekend via de bar. Er moet dus op een manier een iButton lezer in, en een interface naar de bar gemaakt worden. Ook lijkt het mij leuk om status updates te doen op het IRC kanaal, vergelijkbaar met deuren die geopend worden.<br /> <br /> === Mogelijke mods om iButton lezer te koppelen ===<br /> Authenticatie bij de door mij gekochte uitvoering van het laadstation werkt door RFID-tags in te programmeren en die te gebruiken als sleutel. RFID wordt verzorgd door een losse module, die door een eigen stuk hardware te emuleren is. Hij zit via RS232 TTL vast aan de rest en heeft een manual, dus met wat logic analyzer magic, RTFM en blijven proberen moet dat wel te gebruiken zijn als aansluit interface voor eigen access control (stukje hardware wat iButtons kan lezen).<br /> <br /> Keba palen kunnen hetgeen wat met RFID kaartjes kan ook via de ethernetpoort, als je genoeg geld neerlegt bij Keba. Het door mij gekochte model is echter de goedkope versie, die deze features &quot;niet heeft&quot; (ofwel het staat uit in de software). De afwezigheid van deze features is waarschijnlijk de reden geweest dat de vorige eigenaar dit laadstation heeft ingeruild voor een nieuwere/duurdere.<br /> <br /> Zoals eerder genoemd bij de Enable-input sectie: Deze is niet te gebruiken voor authorisatie. Deze input is om het laden tijdelijk te onderbreken en weer verder te gaan met laden wanneer er weer zonlicht op de zonnepanelen valt.<br /> <br /> Een andere mod die erg goed blijkt te werken is CP pin onderbreken. Wanneer de CP niet meer verbonden is met de PE pin stopt de software het laden en wordt de stekker ontgrendeld. Bij inpluggen wordt de stekker wel altijd vergrendeld, maar als er geen laadoperatie gestart wordt in ~30 sec. gaat hij alsnog weer los. Ook als de stekker al los is gegaan door de timeout kan alsnog een laadsessie gestart worden door de CP pin weer te verbinden (de stekker vergrendeld dan weer). Dit tezamen met een lege ACL en een relais lijkt de ideale hack om een eigen authorisatie/authenticatiesysteem in te bouwen.<br /> <br /> Voor verbruiksstatistieken en status updates naar IRC zijn de UDP broadcasts op de ethernet poort bruikbaar. Voor de meest actuele verbruiksstand kan ook de output van de webserver gebruikt worden.<br /> <br /> === Mod hardware ===<br /> Ik heb een gen 1. Pi model B, die op de ethernetpoort van de Keba kan. De Pi kan zo de statistieken van de energielevering opvragen (http get) en/of bijhouden (UDP luisteren). Wellicht is het mogelijk automatisch af te rekenen via de bar, zo niet dan wordt om de zoveel tijd handmatig voor iedereen afgerekend. Tevens moet de Pi ook updates naar IRC kunnen sturen. Voor het uitlezen van iButtons wordt gebruik gemaakt van een gemodificeerde Doorduino. Het onderbreken van de CP pin is prima te doen met een relais aangesloten op de Doorduino.<br /> <br /> ==== Raspberry Pi ====<br /> Softwares? Hoe de boel te scripten danwel programmeren in een daemon?<br /> <br /> ==== iButton lezer ====<br /> De Doorduino moet in staat zijn twee staten te hebben. Momenteel openen ze enkel een deur en gaan ze daarna weer terug naar &quot;dicht&quot;. De software moet wat aangepast worden zodat ze een toestand vast houden tot dezelfde button weer contact maakt. Wellicht is het ook wenselijk dat de Doorduino weer terug kan van geauthenticeerd naar ongeauthenticeerd als de auto de laadoperatie onderbreekt (ook de auto kan de CP pin onderbreken; dit emuleren we feitelijk met de relais). En er moet een override via het netwerk zijn, om ellende op afstand te kunnen oplossen.<br /> <br /> Puntsgewijs:<br /> * Tussen toestanden geauthenticeerd en ongeauthenticeerd schakelen door aanbieden iButton<br /> * Toestand vasthouden<br /> * Naar de toestand ongeauthenticeerd schakelen als de laadsessie vanaf de auto wordt onderbroken?<br /> * Gebruikersnaam deelnemer aan Raspberry Pi communiceren (voor vastleggen verbruik per gebruiker, IRC updates)<br /> * Override voor schakelen geauthenticeerd en ongeauthenticeerd via het netwerk, ofwel via Raspberry Pi<br /> <br /> == Reverse-engineering ==<br /> Initieel ligt de focus op het realiseren van een laadpunt. Later gaan we de hardware en software nog reverse-engineeren. Voor shits &amp; giggles, en wie weet wat er allemaal nog mogelijk blijkt (hint: die UDP aansturingsfeatures zijn wel leuk om te hebben).<br /> <br /> Paar losse flarden info:<br /> * lwIP (lightweight IP) TCP/IP stack<br /> * Contiki als OS?</div>

<p>Mux: </p> <hr /> <div> {{Project<br /> |Name = Laadpunt<br /> |Picture = Keba_P20.jpg<br /> |Omschrijving = Een laadpunt voor elektrische auto's @Revspace<br /> |Status = In progress<br /> |Contact = merethan<br /> }}<br /> <br /> Er komen meer en meer [https://www.anwb.nl/auto/themas/elektrisch-rijden/ elektrische auto's] op de Nederlandse wegen. Een groot nadeel van deze voertuigen is dat accu's in vergelijking met een brandstoftank nog altijd wat beperkt zijn in hoeveel energie ze kunnen vasthouden. Om lekker rond te kunnen karren heb je dus wat vaker toegang nodig tot een [https://oplaadpalen.nl/ stopcontact] dan dat je een brandstof auto moet tanken. Niet alleen vaker, maar ook langer, want het laden duurt even.<br /> <br /> Omdat het laden even duurt is het daarom handig een stopcontact te hebben op de plek waar je heen gaat. Terwijl je ergens bent kan je auto dan opladen. Revspace is zo'n plek waar ik regelmatig ben, maar tot nu toe geen &quot;echt&quot; laadpunt was.<br /> <br /> Sinds september 2016 heb ik een [https://en.wikipedia.org/wiki/Renault_Twizy Renault Twizy]. Daar heb je eigenlijk geen &quot;echt&quot; laadpunt voor nodig, want hij laad slechts met 230VAC 10A (enkele fase). Er zit dan ook een doodnormale [https://en.wikipedia.org/wiki/Schuko Schuko] stekker aan, en niet de in Europa voor auto's bekende [https://en.wikipedia.org/wiki/Type_2_connector Mennekes Type 2]. Wanneer ik wat laag aan de acculading zat deed ik mijn Twizy dan ook via een normaal (geschikt) verlengsnoer opladen bij Revspace. Vanaf het begin waren er al geluiden dat dit problemen kon gaan geven omdat het niet echt als &quot;fair use&quot; te verkopen valt aan de partij waarvan Revspace het pand van huurt. Maar gezien de Twizy niet een &quot;echte&quot; auto was en ik het niet heel vaak deed, werd een oogje toe geknepen.<br /> <br /> Sinds ergens begin 2018 heeft [[mux]] echter ook een elektrische kar, namelijk een 1st gen. [https://en.wikipedia.org/wiki/Nissan_leaf Nissan Leaf] (binnenkort met extra 18650's uitgerust, I kid you not). Toen die ook kwam laden was de pand eigenaar &quot;not amused&quot;. Nu er meer en ook grotere rijdende accu's Revspace aandoen, hebben we dus een &quot;echt&quot; laadpunt nodig, die stroom per &quot;klant&quot; afrekent; gezien het significante stroomverbruik tijdens het laden van voertuigen kan dit niet meer onder de elektra fair use policy van de rest van de space geschaard worden.<br /> <br /> == Tijdelijke administratie kWh's ==<br /> <br /> Totdat we een werkend laadpunt met automatische afrekening hebben, houden we hier bij hoeveel er geladen wordt.<br /> <br /> Mux:<br /> <br /> * ?? Februari: 12 kWh<br /> * Wo 11 april: 3 kWh<br /> * Ma 30 april: 16 kWh<br /> * Di 1 mei: in progress<br /> <br /> == Het laadpunt ==<br /> Momenteel zijn er twee laadpunten in bouw. [[Mux]] heeft er voor gekozen allerhande spulletjes uit China over te laten komen, en uit componenten zelf iets te fabriceren. Ik ([[merethan]]) heb er voor gekozen naar een tweede hands of kapotte op zoek te gaan, en die net zo lang te hacken tot het doet wat ik wil. Ik heb wat rond gezocht en gemaild, waarna ik reactie van [https://www.laadpunt.nl/ laadpunt.nl] heb gekregen. Die hadden nog een ingeruilde liggen, die ik voor een relatief zacht prijsje mocht overnemen, mits ik er ook echt wat boeiends mee ging doen. Dank aan laadpunt.nl daarvoor.<br /> <br /> === Keba P20 ===<br /> [[File:Keba_P20_tweedehandsje.jpg|200px|thumb|right|De Keba P20 gekocht door merethan]]<br /> Het apparaat betreft een [https://www.keba.com/web/downloads/e-mobility/KeContact_KCP20_30_ih_en.pdf Keba KeContact P20]. Hij heeft reeds ruim 2 jaar dienst gedaan bij de vorige eigenaar. De vorige eigenaar heeft 'em ingeruild voor een nieuwer en geavanceerder model, naar verluid omdat hij/zij meer management opties wilde.<br /> <br /> ==== Keba AG ====<br /> [http://www.keba.com/ Keba AG.] is een Oostenrijks bedrijf wat actief is in meerdere markten. Voor ze laadpalen zijn gaan maken deden ze al allerhande andere automatisering, waaronder machines voor plastic gieten, metaalbewerking, kluisjessystemen en bankautomaten (flappentappen &amp; contant deposit).<br /> <br /> ==== Specs &amp; features ====<br /> [[File:Keba_P20_tweedehandsje_open.jpg|200px|thumb|right|De Keba P20 geopend]]<br /> Het volledige modelnummer is: KC-P20-ES240010-00R. De installatiehandleiding bevat een handig tabelletje om dat te decoderen. Het komt neer op het volgende:<br /> KeContact, model P20, Europese uitvoering, met een Socket (ipv vaste kabel), 2 = Mennekes Type-2, 4 = 32A versie, 00 = 0 meter kabel (duh..), 1 = b-series model, 0 = &quot;Contactor electrics&quot; (wut??), 00R = met RFID uitgevoerd.<br /> <br /> Het betreft dus, gezien het 3-fase 230V op 32A is, een 22kW laadpunt.<br /> <br /> ==== Installatie ====<br /> Het apparaat moet upstream afgezekerd worden met een automaat die bij de specs van de bekabeling past en een eigen aardlekschakelaar. Ook moet het maximale laadvermogen dmv DIP-switches ingesteld worden, zodat de paal dit kan communiceren aan de auto.<br /> <br /> == Interfaces ==<br /> Het apparaat heeft meerdere interfaces via welke het interactie heeft met de rest van de wereld.<br /> <br /> === Mennekes Type 2 plug met SAE J1772 signallering ===<br /> !! Mux moet deze sectie nog fact-checken en aanvullen !!&lt;br&gt;<br /> De meest elementaire interface aan het laadpunt is het stopcontact voor de auto: De [https://en.wikipedia.org/wiki/Type_2_connector Mennekes Type 2] connector. Deze bevat naast een PE, N, L1, L2 en L3 (de pinnen die je kent van krachtstroom) ook nog de pinnen PP (proximity pilot) en CP (control pilot). Via PP en CP communiceren de auto, de kabel en het laadsysteem hoeveel vermogen er getrokken mag worden. De logica hierachter is echt heel low-tech en niet uniek voor deze plug. Het &quot;protocol&quot; is namelijk overgenomen van een andere standaard: De Japans/Amerikaanse [https://en.wikipedia.org/wiki/SAE_J1772 SAE J1772] plug.<br /> <br /> Via de PP pin laat de kabel (de stekker eigenlijk) weten voor hoeveel ampère de kabel geschikt is. Dit werkt zeer low-tech: Een bepaalde weerstand tussen de +12V PP pin en de PE pin codeert van welke klasse de kabel is. Via deze pin kan zowel de auto als het laadstation dus ook detecteren wanneer er een kabel ingeplugd is. De PP pin is ook korter dan de andere pinnen, zodat het laadstation of de auto de stroom kan afschakelen voordat de rest van de pinnen contact verliezen (dit om vonken te voorkomen). De PP pin is niet van de ene naar de andere kant van de kabel verbonden.<br /> <br /> De CP pin is wel verbonden door de kabel heen, wat de auto en het laadpunt in staat stelt om te communiceren met elkaar. Again, dit werkt zeer low-tech: Het laadpunt zet een square-wave van ±12V (-12V tot +12V) op de CP pin, met een frequentie van 1Khz. Als de PWM 1Khz. is betekent dat dat de auto &quot;vol vermogen&quot; mag trekken. Hoe lager de frequentie, hoe minder amps de auto mag trekken. Online zijn tabellen te vinden van welke PWM cycle hoeveel ampères betekent.<br /> <br /> De CP pin is aan de auto kant verbonden met de PE pin via een weerstand en een diode. Omdat maar de helft van de ±12V square-wave afgevlakt wordt (diode) weet het laadstation dat het snoer ook echt in een auto zit en niet in de regen ligt. De weerstand die de auto tussen CP en PE plaatst codeert verschillende &quot;staten&quot; waarin de auto zich bevind. Zo is er bijvoorbeeld een specifieke weerstand waarmee de auto aan het laadsation aangeeft dat hij wil gaan laden. Online zijn tabellen te vinden met welke weerstand welke staat codeert.<br /> <br /> Meer diepgaande uitleg en tabellen van coderingen is [https://en.wikipedia.org/wiki/SAE_J1772#Signaling op Wikipedia] te vinden.<br /> <br /> Voor de duidelijkheid: Het laadpunt is enkel een circuit breaker. Het laadpunt doet niets in de trand van power duty cycle regeling. Als de auto meer amps trekt dan het door het laadpunt opgegeven maximum, gaat de stroom gewoon uit.<br /> <br /> === GreenPhy protocol ===<br /> Het laadstation ondersteunt ook PLC (Power Line Communication) met de auto dmv het [https://en.wikipedia.org/wiki/HomePlug#HomePlug_Green_PHY GreenPhy protocol]. Voor wat ik er nu van begrijp stelt dat de auto in staat om via de AC kabels op 10mbit te communiceren met het LAN waar het laadpunt aan vast zit. Zeer vergelijkbaar met &quot;power line ethernet&quot; wat je binnen je huis kunt doen, als je te lui bent om kabels te trekken.<br /> <br /> === RFID ===<br /> Bijna alle laadstations hebben een methode voor authorisatie/authenticatie. Het authorisatie/authenticatiesysteem van het door mij gekochte model werkt op basis van RFID tokens. RFID functionaliteit wordt verzorgd door een [http://www.hopt-schuler.com/33771/Products/Card-Readers/RFID-card-readers/RFID-card-readers/881/productlist.aspx ddm Hopt+Schuler 881 module] ([https://www.microtron.be/wp-content/uploads/2016/10/Hopt-Schuler-881.pdf datasheet]). Deze reader is compatible met Mifare/ISO14443/ISO15693 tokens. Voor zover ik het systeem nu begrijp blaft de module gewoon het serienummer van de gepresenteerde token over een RS232 TTL lijn heen en dat is dan de sleutel.<br /> <br /> === Enable-input ===<br /> Binnenin het laadstation zit een enable-input (terminal X1) voor interfacing met een ander systeem. Door deze terminal kort te sluiten is het systeem &quot;enabled&quot;. Hierin slaat &quot;enabled&quot; niet op authorisatie: Deze input schakelt het laden aan of uit, maar voorkomt aankoppelen niet. Dus als de enable-input onderbroken (uit) is, en iemand koppelt een kabel/auto aan, dan wordt die wel gelocked en begint initialisatie van het laadproces. Laden (stroom leveren) begint echter pas als je X1 kortsluit. (Dat zou je bijvoorbeeld kunnen gebruiken icm een zonnepanelen systeem, zodat je enkel overcapaciteit in je auto laad.) De enable-input is dus geen access control systeem of te gebruiken om een access control systeem op aan te sluiten.<br /> <br /> === Ethernet ===<br /> De Keba P20 heeft een ethernetpoortje (terminal X3). De IP instellingen zijn te regelen met de DIP-switches. Momenteel gebruikt het apparaat 192.168.25.11 als adres.<br /> <br /> ==== UDP input ====<br /> Keba laadpunten ondersteunen volgens de UDP programmers manual een setje commando's die je via ethernet kunt sturen. Dit zijn simpele tekst-gebaseerde commando's over UDP, op poort 7090. Open een shell met 'netcat -l -p 7090 -u -b 192.168.25.11 7090' om te luisteren, ga in een andere shell commando's sturen met 'echo -n &quot;[command]&quot; | netcat -q 0 -u 192.168.25.11 7090', en je bent in business.<br /> <br /> De door mij gekochte versie is echter het instapmodel, en ondersteunt daarom vrijwel niks van wat in de UDP manual van Keba staat.

En dat was het.<br /> <br /> ==== UDP output ====<br /> De ethernetpoort is niet geheel waardeloos, want hij doet wel nuttige UDP broadcasts.

Unfortunately, whereas we have stockpiled quite a fun assortment of chemicals, we are still missing a lot of glassware, equipment and above all a safe environment to do proper chemistry in. Project FumeHood will change this.<br /> <br /> This project aims to provide a complete environment to safely do a very wide variety of chemistry experiments by:<br /> * Providing a safe fume cupboard, made from chemically inert materials, to do the experiments in<br /> * Providing within the fume cupboard all the amenities you expect in a proper chemistry lab: electric outlets, gas connections, water connections, vacuum takeoff and of course air extraction through a carbon filter<br /> * Providing dedicated, safe storage for glassware and chemicals<br /> * Buying, as part of the project, a wide assortment of compatible glassware<br /> * Buying a few necessary chemicals<br /> * Buying, separately, a hot plate stirrer<br /> <br /> The fume hood will be located in the Werkplaats, right next to the exit, facing the lounge.<br /> <br /> == Fume Hood construction ==<br /> <br /> Some fume hood construction details:<br /> * Table height: 85cm<br /> * Cupboard inside height: min 95cm<br /> * Width: min. 110cm (up to 140cm outside size is possible)<br /> * Outside depth: 60-80cm<br /> * Compartmentalized storage underneath fume cupboard, with doors<br /> * Special mini-compartment with safe for extremely hazardous chemical storage<br /> * Inside of fume cupboard is lined with glass fiber, possibly with white PC sheet cladding for easy cleaning<br /> * Glass fiber is reinforced with aramid fiber bands for explosion-proofness<br /> * Table is toughened glass, for easy cleaning and chemical resistance<br /> * Two steel bars run along the back and top with holes tapped with M8 threads every 10cm; lab stand-style rods can screw into these<br /> * Polycabonate sheet single slide-up door with glove holes, on spring-loaded linear guides and with simple up/down retaining latches<br /> * Main skeleton out of wood<br /> * Connections on the inside: <br /> ** 2x230V IP44 PVC outlets<br /> ** 2x barbed hose connectors for water (to water mains or circulating pump)<br /> ** 1x barbed hose connector for bunsen gas/argon<br /> ** 1x special (?) connector for vacuum take-off (vacuum pump can sit on the table besides the fume cupboard)<br /> * Dedicated fuse box on the side of the fume cupboard?<br /> * Soviet army style cylindrical carbon filter on the exhaust, followed by a 450m3/h or more fan<br /> * Table has a 2cm+ lip to contain spills. Caulked or epoxied to glass fiber all around.<br /> * Fire door. No automatic fire suppression.<br /> <br /> == Glassware ==<br /> <br /> We will be ordering the following glassware, all 29/32:<br /> * Rods, clips and connectors for latticebuilding<br /> * 600mm Leibig condenser<br /> * 400mm Vigureaux fractional distillation column<br /> * 500mm Dimroth condenser<br /> * Thermometer stopper<br /> * Vacuum takeoff<br /> * Parallel neck adapter<br /> * 75 deg adapter (distillation setups, etc.)<br /> * Glass stoppers<br /> * Soxhlet extractor (+possibly joint)<br /> * 50, 100, 250 and 500ml roundbottom flasks<br /> * Keck clips<br /> * A 500ml drop funnel (which we'll abuse as a separatory funnel as well)<br /> * Waste bottles (soda lime glass) + caps<br /> * Reaction plates and crucibles<br /> <br /> == What are we going to do with the fume hood? ==<br /> <br /> Of course, we're not building a big, expensive project like this just for the fun of construction. We do intend on doing a fair amount of cool chemistry. A nonexhaustive list of the projects thought up so far:<br /> <br /> * Making a lithium-ion battery (also involves project Smeltoven)<br /> * Gold, palladium and platinum recovery from computer components using the cyanide pathway (also involves project Smeltoven)<br /> * Chip decapping<br /> * Making sodium and/or potassium metal using the new Nurdrage method<br /> * Playing with project DIY solid-state stirrer<br /> * Anodizing aluminum (and doing it right this time!)<br /> * Making sodium silicide (for hydrogen production)<br /> * Demonstration project: glowsticks (TCPO method)<br /> * Demonstration project: copper salt crystal growth<br /> * Demonstration project: basic electrolysis<br /> * Demonstration project: Clock reaction<br /> * Making aerogels<br /> * Synthesizing organic and inorganic dyes</div>

They're not just nice things to look at, they are also surprisingly practical in daily life. Combining these two ideas, it seems like a nice idea to make a bicycle that can be used by any member of Revspace for daily errands, and that also acts as advertising for the hackerspace.<br /> <br /> == Project requirements ==<br /> <br /> The bicycle should:<br /> * Be immediately usable by anyone. No weird model, no modifications that make it hard to use, no recumbents.<br /> * Be convenient and inviting to use. No weird procedures to turn it on, not much the user can do wrong, easy to lock. It probably helps to make it electric.<br /> * Showcase all major competences of the hackerspace in an obvious and explicit way. When looking at it, it should be obvious you're looking at an ad for an awesome place for nerds. Non-technical people should be intrigued and not immediately appalled.<br /> * Be aesthetically/technically coherent<br /> * Be low-maintenance<br /> * Be reasonably cheap<br /> <br /> == Concept ==<br /> <br /> '''This entire paragraph is subject to sweeping change'''<br /> <br /> The concept I (mux) have for this bike, is to take a bike with the following properties:<br /> * A cheap, second hand but decent quality (ideally one of the big 4 brands) electric bike as a basis<br /> * For males (i.e. main frame triangle) so we can fit batteries and TFT displays in the triangle<br /> * Low seat height with toolless adjustable long (350mm?) seat post so anybody can ride it<br /> * Internal gear hub, closed chainguard/box and Rollerbrakes (so we don't have any maintenance on those)<br /> * Ideally an aluminum frame and exposed parts, so we don't have issues keeping it outside in the rain<br /> * Fixed, by default EMPTY (no electronics inside them) pannier bags. <br /> <br /> And then of course the features:<br /> * As big as possible TFT screens and a raspberry pi (equivalent) showing random shit on those screens when it's parked and on (i.e. standing somewhere near stores)<br /> * Lots of LED strips. Note: These are not allowed to be on when riding. <br /> * Lots of sensors. Power, pedal power, air quality, speed, GPS, whatever<br /> * Ideally some kind of internet connection, or maybe a possibility to hitchhike on users' phone plans? This may be acceptably cheap for revspace to pay out of an advertising budget.<br /> <br /> ==The bike!==<br /> <br /> We have bought an ANWB (2010-11 era) NiMH electric bike. It is gearless, 2x26&quot; low aluminum frame, with an toolless adjustable long seatpost. So it's very simple, virtually maintenance free and (hopefully) pretty foolproof. <br /> <br /> The motor is a 250W DC brushed motor. The bike runs on 24V, originally NiMH. At the moment, the battery has been fitted with a 6S4P li-ion battery (approx. 120Wh).<br /> <br /> ==To-Do list==<br /> <br /> The spacebike needs to have a lot of work done. The work falls under three categories: must-haves, nice-to-haves and cool projects.<br /> <br /> Must-haves:<br /> * The bike 'cage' where it is stationed now should be made iButton-accessible<br /> * The handlebar handles are sticky. They have to be replaced<br /> * The battery is woefully underpowered, it needs better cells<br /> * Rear and front light should be upgraded to something that is automatic and doesn't run on separate batteries<br /> * The bell is annoyingly loose, should be replaced<br /> * Brakes should be adjusted to be a bit more responsive<br /> <br /> Nice-to-haves:<br /> * The battery indicator is permanently on when the battery is in. That should be fixed to avoid undervoltage on the battery.<br /> * Front wheel can be outfitted with a rollerbrake instead of rim brake for reduced maintenance<br /> * The rear wheel uses a springy force sensor, it's a bit annoying that it has so much travel. Every wheel rotation it feels like the pedals don't 'connect' well.<br /> <br /> Spacebike should be regarded as a community project; everyone can contribute something. That being said, projects need to adhere to the following requirements:<br /> * Your project should not cause dangerous situations. If it makes light and isn't a front or rear light, it should be OFF when the bike is moving (unless you have a very good reason to keep it on). The mounting position should not inhibit the rider or reduce carrying capacity.<br /> * Your project should be weatherproof, IP67.<br /> * If your project needs electricity, it needs to work on 24V +/- 10% with spikes up to 32V<br /> <br /> Projects<br /> * Building a bigger battery. Currently, the bike's range is only about 10km. <br /> * Making the battery actually watertight and giving it a proper IP67 charging port<br /> * Making an iButton bike lock. That should be really cool :)<br /> * Building storage space on the back of the bike<br /> * Making 24V distribution all over the bike<br /> * Adding a phone holder and USB charger to the handlebars<br /> * Building a computer into the bike that can drive a set of screens and process sensor data.<br /> * Adding all kinds of sensors to the bike: light, rain, speed, GPS, tire pressure, voltage, power, whatever you can think of<br /> * Building a trailer for the bike</div>

Een leuke hobby maar ook een uitdaging. De middelen zijn beperkt. Enkele ingrediënten zijn &quot;aanwezig op de space&quot;. Dat wil zeggen dat ze &quot;aanwezig&quot; zijn als je dat hebt gecontroleerd, geen garanties.<br /> <br /> ==Keukeninventaris==<br /> * Inductiekooktoestel (2x 1 pit)<br /> * Combi-magnetron (kleintje)<br /> * Wokpan<br /> * Koekenpan<br /> * Grote Ikea pan (10L)<br /> * Snijplanken<br /> * Messen<br /> * Spatels<br /> * Blikopener<br /> * Stamppot-stamper<br /> <br /> ==Geteste recepten==<br /> ===Yoghurt-Knoflooksaus===<br /> Dit recept is nog grotendeels 'op gevoel'...<br /> * 1kg Griekse Yoghurt<br /> * Enkele eetlepels Calvé Yofresh Mayonaise<br /> * Halve bol knoflook<br /> * Handje fijn gehakte bieslook<br /> * Dille<br /> * Ketjap<br /> * Zout/Peper<br /> <br /> ===Vlaamsche pot===<br /> Voor 4 personen met onderstaande hoeveelheden. Circa €4,00 a €4,50 pp:<br /> * 8 Roseval aardappeltjes (of andere vastkokende)<br /> * 2 grote uien<br /> * 2 grote winterpenen<br /> * 2 pastinaken<br /> * 4 tenen knoflook<br /> * Rozemarijn (vers)<br /> * Grof gemalen zwarte peper en willekeurig zout<br /> * Olie<br /> * 4 kippenbouten groot, naturel<br /> * Zaanse (of Vlaamsche) mayonaise<br /> * Appelmoes<br /> <br /> <br /> Maak alle groente schoon en snij alles in grove stukken. Gooi alles in een braadpan en doe er wat zout, peper, rozemarijn en olie bij. Zet dit op een laag vuur en doe de deksel dicht. Roer eens per 5 minuten om zodat het niet aanbakt. <br /> <br /> Kruid de kip: Gooi wat peper, zout, rozemarijn, olie en knoflook in de vijzel en maal dit tot een kruidenpasta. Het beste is deze pasta onderhuids aan te brengen (bij de kip).<br /> <br /> Grill ondertussen de kippenbouten. Na een half uur grillen en bakken is het wel gaar (controleer wel de kip!)<br /> <br /> Serveer de mayo en appelmoes bij de pot.<br /> <br /> Eet smakelijk!<br /> <br /> ===Nasi Goreng===<br /> Voor 10 personen met onderstaande hoeveelheden. Circa €2,50 a €3,00 pp:<br /> * Conimex Boemboe Nasi Goreng<br /> * 500gr Basmati rijst (mogelijk aanwezig op space)<br /> * 350gr Nasi/Bami Vlees<br /> * 300gr Spekreepjes<br /> * 700gr Nasi/Bami groente<br /> * 10x AH Basic Kipsate<br /> * 2 EL Ketjap Manis (aanwezig op space)<br /> * 1 EL Ketjap Asin (aanwezig op space)<br /> * 4 zakken kroepoek (2x Cassave en 2x regulier)<br /> * 12 eieren<br /> * Atjar (mogelijk aanwezig op space)<br /> * Gebakken uitjes (mogelijk aanwezig op space)<br /> * Seroendeng (mogelijk aanwezig op space)<br /> * Wokolie (aanwezig op space)<br /> <br /> Rijst koken (8 minuten in kokend water, afgieten en apart zetten). Pepers ontdoen van zaadlijsten, snipperen. Spek uitbakken in wokolie, vlees bruin bakken. Groenten 2 minuten meebakken. Twee eieren toevoegen aan mix en losroeren. Boemboe en 50ml water toevoegen. Vlees/groentemengsel toevoegen aan rijst in grote schaal, goed roeren met 2 EL Ketjap Manis en 1 EL Ketjap Asin. Rustig af laten koelen.<br /> <br /> Sate verwarmen in pan heet water. Apart zetten.<br /> <br /> Eieren bakken naar smaak. <br /> <br /> Nasi afbakken in wok.<br /> <br /> Smakelijk eten!<br /> <br /> ===Coq Au Camping===<br /> [http://www.ah.nl/allerhande/recept/R-R830856/coq-au-camping Recept op AH.nl]<br /> Was goed te verdubbelen, prima smaak. Past niet in de wok, je kunt net zo goed direct in de grote pan beginnen. Aangekoekte meuk komt toch los met de rode wijn. Kleinere kipstukjes genomen (vleugeltjes doormidden gehakt) (mogelijk is kipdijfilet of gewoon kipfilet fijner, zonder botjes). Celavita minikrieltjes zijn ietsje duurder maar wel lekkerder en sneller gaar. In tweede ronde twee teentjes knoflook toegevoegd: heerlijk!<br /> <br /> Nieuwe iteratie gedaan. Weer een dubbele portie. Champignons en uien iets fijner gesneden, dan past alles beter. Kipdijfilet in reepjes gesneden en ruim van paprikapoeder en peper voorzien (en wat zout). Direct in de hoge pan gewerkt, ging prima. Geserveerd met sla en stokbrood, tien man van eten voorzien.<br /> <br /> ===Paëlla===<br /> [http://www.ah.nl/allerhande/recept/R-R726314/paella-met-kip-en-gamba-s Recept op AH.nl]<br /> Heerlijk gegeten. Goed te verdubbelen maar past nét niet in de wok op het einde als de erwten en zeefruit er in moeten. Kipdijfilet is een must. Goede Chorizo ook. Reguliere paprika ipv puntpaprika gebruikt. Diepvrieszak Zeefruit gebruikt ipv alleen Gamba's. Was al gaar, wel zo makkelijk en meer variatie. Zonder salade voor ongeveer 10 man te eten, met salade lukt 12 ook wel.<br /> <br /> ===Chili con Carne===<br /> [http://www.ah.nl/allerhande/recept/R-R321046/chili-con-carne Recept op AH.nl]<br /> Super. Geserveerd met ruime salade. Met z'n 12en gegeten, er hadden nog 1 of 2 meer mee kunnen eten. Recept verdrievoudigd. Twee dozen tomatenblokjes toegevoegd en iets meer water dan voorgeschreven. Ook een mix van diverse soorten bonen gebruikt (kidney, bruin en zwart). Absoluut maximum van wat met onze pannen te maken is qua volume. Iets langer door laten garen vanwege de sperziebonen. <br /> Gebruikte kruidenmix: http://www.ah.nl/producten/product/wi237932/mesa-mexicana-chili-seasoning-mix<br /> <br /> ===Mediterrane stamppot===<br /> [http://www.ah.nl/allerhande/recept/R-R1186188/mediterrane-stamppot-met-rookworst Recept op AH.nl]<br /> Lekker. Met onze huidige setup max 8 personen (verdubbeld, geserveerd met stokbrood en sla). <br /> <br /> Wel het nodige veranderd/verbeterd. Om het voor 1 pit geschikt te maken eerst de 'saus' gemaakt. In plaats van rookworst een mixschotel chipolata-braadworstjes gebruikt (in stukjes gesneden). Ik vermoed dat Catelaanse braadworsten nog meer smaak geven. Heeft wel wat zout/peper nodig. Mogelijk nog wat Provençaalse of italiaanse kruiden toevoegen voor wat meer diepgang.<br /> <br /> ===Pasta Bolognese===<br /> ''Voor 10 hackers''<br /> * 1250 gram Tagliatelle<br /> * 500 gram rundergehakt<br /> * Zak Italiaanse roerbakmix (400/500 gram)<br /> * Doosje Champignons (250 gram)<br /> * 2 dozen gezeefde tomaten<br /> * 2 blikken gepelde tomaten of dozen tomatenblokjes<br /> * 2 uien<br /> * 3 tenen knoflook<br /> * 2 eetlepels gembersiroop (al op de space aanwezig)<br /> * Flinke zak geraspte kaas (500gr)<br /> * Pot Pastakaas-poeder<br /> * Half bouillonblokje kip of rund<br /> * Halve pot gevriesdroogde italiaanse kruiden (dat groene spul, niet de bruine meuk!)<br /> * Standaard Hacker Sla (2 komkommers, 2 rode paprika's, zakje wortelrasp, zakje Ruccola, 4 tomaten)<br /> * Standaard stokbrood (2 stokbroden)<br /> * Olijfolie<br /> * Zout en peper (aanwezig op de space)<br /> <br /> ====Saus====<br /> Snipper de champignons, ui en knoflook. Fruit de ui in een beetje olie op laag vuur, 5 minuten tot ze mooi glazig en lichtbruin zijn (dan komen de suikers vrij). Voeg de gehakt toe, samen met de knoflook, een halve pot italiaanse kruiden en flink peper (je maalt over het vlees een volle ronde peper). Bakken op middelhoog tot het gehakt rul is, en kleur begint te krijgen.<br /> <br /> Voeg de groentenmix en champignons toe en bak deze een 2 minuten mee. Regelmatig omscheppen!<br /> <br /> Voeg de gezeefde tomaten, gepelde tomaten (even klein hakken!), de gembersiroop en een half verkruimeld bouillonblokje toe. Breng aan de kook. Laat een paar minuten sudderen. Regelmatig roeren!<br /> <br /> De saus is in principe klaar. Proeven!<br /> <br /> ====Pasta en salade====<br /> Haal de wok van de pit en zet de pan met heet water op (ruim, driekwart vol) met een flink schot zout. Breng aan de kook. Tagliatelle er in. Gedurende het koken (ca 10 a 12 minuten) regelmatig roeren. <br /> <br /> Snijd alle slacomponenten en maak de salade. Dressing vlak voor het eten pas toevoegen, anders heb je slappe sla.<br /> <br /> Stokbrood snijden, kruidenboter klaarzetten.<br /> <br /> Zodra de pasta beetgaar is (hij gaart nog iets door tijdens afgieten en op tafel) afgieten. Scheutje olie erin, roeren, en daarna de saus er doorheen scheppen. Doe dit met beleid, anders maak je er een dikke klont pasta van. <br /> <br /> Eet smakelijk!<br /> <br /> ====Variatietips====<br /> * Een beetje Sambal of een rood pepertje?<br /> <br /> ===Hutspot===<br /> Voor 12 hackers<br /> * 3x zak hutspot 1kg<br /> * 3x zak stamppotaardappelen 600gr<br /> * Knoflook (3 tenen)<br /> * 4x bakje Catelaanse braadworsten (3 worsten per bakje, eventueel meer vleesch aanschaffen)<br /> * Potje Maggi Juspoeder<br /> * Standaard Revspace Salade (2x komkommer, 6x tomaat, 2x paprika, 2x zakje sla, sladressing)<br /> * Standaard stokbrood/kruidenboter<br /> <br /> Vlees braden, knoflook toevoegen, kort meebakken. Jus aanmaken en vlees laten sudderen. Laat een minion de sla bereiden.<br /> <br /> Pan vullen met aardappels en de wortel/ui mix en water (flink zouten). Aan de kook brengen. Na 20 minuten koken aardappels prikken of ze gaar zijn. Zo ja: afgieten en weer even opzetten (wat water laten verdampen). Daarna stampen met flink peper en eventueel nog wat zout. Vlees nog even opzetten. <br /> <br /> Eet smakelijk!<br /> <br /> ====Variatietips====<br /> * Nasikruiden (ik vermoed 2 zakjes) wellen en toevoegen tijdens het stampen met sambal<br /> * Zout tijdens koken vervangen voor 2 of 3 bouillonblokjes<br /> * Spekblokjes/reepjes goed uitbakken (voordat je aan het vlees begint, uit laten lekken op keukenpapier) en na het stampen erdoor scheppen<br /> <br /> ===Pannenkoeken===<br /> <br /> Dit vooral ter referentie voor de hoeveelheden. Voor 6 hackers:<br /> * 2 liter melk<br /> * 1kg bloem<br /> * 2-3 eieren<br /> * Meer dan een snufje zout<br /> * 2 pakjes spek<br /> * Margarine of boter om in te bakken<br /> <br /> Kaaspannenkoeken lijken niet heel erg in de smaak te vallen. 18 hackers konden niet eens 400g kaas aan kaaspannenkoeken (ca. 1 grote plak per pannenkoek) op. Appel en andere variaties zijn nog niet getest op populariteit<br /> <br /> Dingen die goed werken op pannenkoeken:<br /> * Kaneelsuiker<br /> * Schenkstroop<br /> * Jam<br /> * Roomijs<br /> * (spuit)Slagroom<br /> * vruchtencocktail<br /> * Als het grootendeels suiker is, werkt het waarschijnlijk wel<br /> <br /> Je hoeft deze dingen niet groot in te kopen; 18 hackers kregen niet eens een halve pot schenkstroop leeg, en dat was de meestgebruikte topping.<br /> <br /> Verdere tips:<br /> * Als je enigszins bedreven bent, kun je op 3 pitten tegelijk pannenkoeken bakken. Dit kan de stoppenkast nèt aan. <br /> * Je doet ongeveer 30 minuten over pannenkoeken bakken voor 6 man, exclusief voorbereiding<br /> * Pannenkoekenbeslag moet ongeveer de consistentie van dikke karnemelk hebben. Als het Brinta/yoghurtconsistentie heeft, ben je uitgeschoten met de bloem en krijg je te dikke pannenkoeken<br /> * Pannenkoeken zijn klaar om om te draaien als de randjes beginnen te wijken van de pan<br /> * de metalen soeplepel is precies de juiste maat voor de hoeveelheid beslag per pannenkoek<br /> * Stapel je pannenkoeken op een bord op een pan met heet water. Dan blijven ze warm<br /> <br /> ==Handige Sides==<br /> ===Standaard salade===<br /> per 6 hackers (ongeveer)<br /> * Komkommer<br /> * 3 tomaten<br /> * half zakje wortel rasp<br /> * 100/150g gemengde sla of ruccolamix oid<br /> <br /> Uit te breiden met een paprika, radijs, blikje mais oid. Ik kies er meestal voor om als er veel paprika in het hoofdgerecht zit, dat weg te laten in de sla. Hetzelfde met wortel als je bv hutspot maakt.<br /> <br /> ===Stokbrood===<br /> Altijd lekker. Stokbrood is voor een hacker of 5 ongeveer, hangt af van het hoofdgerecht.<br /> <br /> == Morphjes Sauzenfabriek ==<br /> [[ Knoflooksaus ]]<br /> <br /> ==Ongeteste recepten==<br /> <br /> === Oesterzwammensoep ===<br /> Uitjes, knoflook fruiten. Bouillon en oesterzwammen erbij (in stukjes). Laten koken en zacht worden. Staafmixeren, kookroom en dragon erover.<br /> <br /> ===Linkjes===<br /> * http://www.ah.nl/allerhande/recept/R-R1187231/aziatische-garnalenomelet-met-wortel-sesamsalade<br /> * http://www.ah.nl/allerhande/recepten-zoeken?Ntt=Pappardelle+met+tomaten-gehaktsaus<br /> * http://www.ah.nl/allerhande/recept/R-R1187233/tomatencouscous-met-komkommer-en-kruidige-kip<br /> * http://www.ah.nl/allerhande/recepten-zoeken?Ntt=Wraps+met+gyros+%26+appel-coleslaw<br /> * http://www.ah.nl/allerhande/recept/R-R1187237/thaise-noedelsalade-met-kip-en-pinda-s<br /> * http://www.ah.nl/allerhande/recept/R-R1187239/rijstsalade-met-omeletreepjes-en-basilicumolie</div>
